Cancer Drugs Shed Light on Rheumatism

Reporter: Irina Robu, PhD

The human body is often described as being ‘at war’. By this, it is meant that the body is constantly under attack from things that are trying to do it harm. These include toxins, bacteria, fungi, parasites and viruses. The human immune system is one of the most effective defense mechanisms known to nature and can sometimes can be overwhelmed by disease. Yet, on occasions our immune systems turn on our own tissue and attack it which can trigger conditions such as type I diabetes, rheumatoid arthritis and lupus.

In the case of rheumatoid arthritis, immune cells start to attack tissues in the joins which causes them to become painful, stiff and swollen. It is known that one third of those who develop rheumatoid arthritis, feel the horrible effects of the disease within two years of its onset. Immunologist Adrian Hayday, which is a researcher at Francis Crick Institute of London says that the current treatment for rheumatoid arthritis require patients to take the drugs for the rest of their lives. But, researchers such as Hayday found an unexpected ally in the battle against autoimmune disease, cancer.

However, there is a positive consequence to the discovery that cancer immunotherapies have the effect of triggering autoimmune diseases and for the first-time rheumatoid arthritis can be detected at the earliest stages. At present, people are not diagnosed with the condition until symptoms have already made their lives so unpleasant, they have gone to see their doctors. As a result, research backed by Cancer Research UK and Arthritis Research UK, has been launched with the aim of uncovering the roots of autoimmune disease from research on cancer patients.

The scientists mentioned stress that their work is only now start and warn that it will still take several years of research to get substantial results. Nevertheless, uncovering the first stages of an autoimmune disease emerging in a person’s body should give researchers a vital lead in ultimately developing treatments that will prevent or halt a range of conditions that currently cause a great deal of misery and require constant medication.

Our immune defenses consist of a range of cells and proteins that notice invading micro-organisms and attack them. The first line of defense, yet, consists of simple physical barriers similar to skin, which blocks invaders from entering your body. When this defense is penetrated, they are attacked by a number of agents. The key cells, leukocytes seek out and destroy disease-causing organisms. Neutrophils rush to the site of an infection and attack invading bacteria. Helper T-cells give instructions to other cells while killer T-cells punch holes in infected cells so that their contents ooze out. After these macrophages clean up the mess left behind.

Another significant agent is the B-cell, which produces antibodies that lock on to sites on the surface of bacteria or viruses and immobilize them until macrophages consume them. These cells can live a long time and can answer quickly following a second exposure to the same infections. In conclusion, suppressor T-cells act when an infection has been distributed with and the immune system needs to be reassured, the killer cells may keep on attacking, as they do in autoimmune diseases. By slowing down the immune system, regulatory T-cells prevent damage to “good” cells.

MRI-guided focused ultrasound (MRgFUS) surgery is a noninvasive thermal ablation method that uses magnetic resonance imaging (MRI) for target definition, treatment planning, and closed-loop control of energy deposition. Ultrasound is a form of energy that can pass through skin, muscle, fat and other soft tissue so no incisions or inserted probes are needed. High intensity focused ultrasound (HIFU) pinpoints a small target and provides a therapeutic effect by raising the temperature high enough to destroy the target with no damage to surrounding tissue. Integrating FUS and MRI as a therapy delivery system allows physicians to localize, target, and monitor in real time, and thus to ablate targeted tissue without damaging normal structures. This precision makes MRgFUS an attractive alternative to surgical resection or radiation therapy of benign and malignant tumors.

 

Hypothalamic hamartoma is a rare, benign (non-cancerous) brain tumor that can cause different types of seizures, cognitive problems or other symptoms. While the exact number of people with hypothalamic hamartomas is not known, it is estimated to occur in 1 out of 200,000 children and teenagers worldwide. In one such case at Nicklaus Children’s Brain Institute, USA the patient was able to return home the following day after FUS, resume normal regular activities and remained seizure free. Patients undergoing standard brain surgery to remove similar tumors are typically hospitalized for several days, require sutures, and are at risk of bleeding and infections.

 

MRgFUS is already approved for the treatment of uterine fibroids. It is in ongoing clinical trials for the treatment of breast, liver, prostate, and brain cancer and for the palliation of pain in bone metastasis. In addition to thermal ablation, FUS, with or without the use of microbubbles, can temporarily change vascular or cell membrane permeability and release or activate various compounds for targeted drug delivery or gene therapy. A disruptive technology, MRgFUS provides new therapeutic approaches and may cause major changes in patient management and several medical disciplines.

Extraordinary Breakthrough in Artificial Eyes and Artificial Muscle Technology

Reporter: Irina Robu, PhD

Metalens, flat surface that use nanostructures to focus light promise to transform optics by replacing the bulky, curved lenses presently used in optical devices with a simple, flat surface.

Scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences designed metalens who are mainly focused on light and minimizes spherical aberrations through a dense pattern of nanostructures, since the information density in each lens will be high due to nanostructures being small.

According to Federico Capasso, “This demonstrates the feasibility of embedded optical zoom and auto focus for a wide range of applications, including cell phone cameras, eyeglasses, and virtual and augmented reality hardware. It also shows the possibility of future optical microscopes, which operate fully electronically and can correct many aberrations simultaneously.”

However, when scientists tried to scale up the lens, the file size of the design alone would balloon up to gigabytes or even terabytes. And as a result, create a new algorithm in order to shrivel the file size to make the metalens flawless with the innovation currently used to create integrated circuits. Afterward, scientists follow the large metalens to an artificial muscle without conceding its ability to focus light. In the human eye, the lens is enclosed by ciliary muscle, which stretches or compresses the lens, changing its shape to adjust its focal length. Scientists at that moment choose a thin, transparent dielectric elastomer with low to attach to the lens.

Within the experiment, when the voltage is applied to elastomers, it stretches, the position of nanopillars on the surface of the lens shift. The scientists as a result show that the lens can focus instantaneous, control abnormalities triggered by astigmatisms, and achieve image shift. Since the adaptive metalens is flat, you can correct those deviations and assimilate diverse optical capabilities onto a single plane of control.

A magnetic wire could replace the lottery of cancer blood tests

Reporter: Irina Robu, PhD

Stanford University scientists developed a magnetic wire which doctors can use to detect cancer before symptoms are detected in patients. The device is threaded into a vein, screens for the disease by attracting scarce and hard to capture tumor cells just like a magnet. The wire would be predominantly valuable to detect ‘silent killers’ such as pancreatic, ovarian and kidney cancer where symptoms only seem in the late stages when it has spread too far to treat. The magnetic wire can save thousands of lives by catching the disease at a time when drugs would be effective. Cells that have broken off a tumor to wander the bloodstream easily can assist as cancer biomarkers signaling the presence of the disease.

Dr. Gambhir’s team published the results in Nature Biomedical Engineering which described how using a wire that has magnetic nano-particles engineered to stick to cancerous cells. The original experiment is on pigs, which are structurally alike to humans and suffer from the same genetic malfunctions that cause cancer. The wire captured 10 to 80 times more tumor cells and was placed in a vein near the pig’s ear which can be removed from and the cells can be used for analysis. In real standings it chosen up 500 to 5,000 more cancerous cells than normal blood samples.

The circulating tumor cells were magnetized with nanoparticles containing an antibody that latch onto them. When attached, the cell carries the tiny magnet around with it and flows past the wire to veer from its regular path in the bloodstream and stick to the wire.  Professor Gambhir hopes that this approach will enrich detection capability and give insight how circulating tumor cells are and how early on they exist once the cancer is present. Once the technology is accepted for humans, the goal is to mature it into a multi-pronged tool that will increase detection, diagnosis, treatment and evaluation of cancer therapy.

It can also be used to gather genetic information about tumors located in places from where it’s hard to take biopsies.

Stem Cells Used as Delivery Truck for Brain Cancer Drugs

Reporter: Irina Robu, PhD

Medulloblastoma, common brain cancer in children has been very difficult to treat therapeutically with traditional interventions which relies on surgical techniques to remove the bulk of the cancerous tissue. The researchers seen the need for novel treatments of medulloblastomas that have recurred, as well as for treatments that are less toxic overall. For this reason, data from University of North Carolina (UNC) Lineberger Comprehensive Cancer Center and  Eshelman School of Pharmacy published a study in PLOS named “Intra-cavity stem cell therapy inhibits tumor progression in a novel murine model of medulloblastoma surgical resection”, validates how cancer-hunting stem cells can track down and deliver a drug to terminate medulloblastoma cells hiding after surgery.

The technology in the research is an extension of a discovery that won researchers a Nobel Prize in 2012 and showed they could transform skin cells into stem cells. The research team started by reprogramming skin cells into stem cells and genetically engineered them to manufacture a substance that becomes toxic to other cells when exposed to another drug. Inserting the drug carries the stem cells into the brain of laboratory models after surgery decreased the size of tumors by 15 times and extended median survival in mice by 133%.

In this study, the scientists indicated they could shrink tumors in murine models of medulloblastoma, hence extending the rodents life. The approach holds promise for reducing side effects and helping more children with medulloblastoma. Amazingly the researchers also developed a laboratory model of medulloblastoma that allowed them to simulate the way standard care is currently delivered—surgery followed by drug therapy. Using this model, they discovered that after surgically removing a tumor, the cancer cells that remained grew faster.

According to the study investigator, Shawn Hingtgen, PhD, the cells are like a FedEx truck that will deliver cytotoxic agents directly into the tumor to a particular location. In earlier studies, Dr. Hingtgen and his colleagues showed that they could flip skin cells into stem cells that hunt and transport cancer-killing drugs to glioblastoma, the deadliest malignant brain tumor in adults.

Medulloblastoma is cancer that happens mostly in kids between ages of three and eight, and while current therapy has changed survival pretty dramatically, it can still be pretty toxic. The ability to use a patient’s own cells to target the tumor directly would be “the holy grail” of therapy, the investigators trust it could hold capacity for other rare, and sometimes fatal, brain cancer types that occur in children as well.

The Convergence of Medical Devices & Drugs: Advances in Drug Delivery May 3, 2018 12:00 PM – 5:00 PM, Westin Hotel, Waltham, MA

Reporter: Aviva Lev-Ari, PhD, RN

Westin Waltham Boston 
70 3rd Avenue Waltham MA US 02451

MassBio’s second annual Medical Device Event will focus on opportunities and advances in drug delivery, including the unique developmental and regulatory challenges these products face, the many scientific advances in the space and new opportunities for funding.  Panelists will discuss innovation and commercialization strategies.

Advances in drug delivery technologies are improving the safety and efficacy of new and existing therapies. The success of many new therapies in development is contingent on the development of effective delivery systems.   Traditional drug delivery methods won’t work for some compounds and biologics.   Stability issues create challenges for storage and transport.  There are opportunities for combination drug delivery products to extend the patent life of drugs on the market.  From diffusion based polymer systems to complex delivery devices utilizing diagnostic sensors and sophisticated control systems for precise and timely delivery of life-saving agents, a diverse set of scientific and engineering disciplines are being brought to bear within this space.  However, combination products involve components that would normally be developed under different types of regulations, design criteria, and controls.  This symposium will explore many of the diverse aspects impacting drug delivery products.

This event will feature an active exhibit hall, panel discussions, a keynote speaker and networking sessions. This is an excellent opportunity for companies to reach a diverse audience that represents nearly every aspect of the life sciences industry, including academic researchers, entrepreneurs, device engineers and biopharma executives.

Clinicians will discuss the medical challenges for which drug delivery innovations have provided a unique solution.  Academic researchers will discuss scientific advances which may lead to breakthrough products.   Entrepreneurs will discuss strategies for funding new product ventures, and development issues specific to drug delivery products.  Corporate speakers will discuss the challenges across the value chain of manufacturing and selling combination products globally.  Regulatory speakers will address current thinking and approaches to drug delivery products within government agencies, both US and internationally.
