New Material Derived From Graphene Improves the Performance of Neuroprostheses

A study has demonstrated in animal models how a graphene derivative allows the creation of smaller electrodes, which can interact more selectively with the nerves they stimulate, thus improving the efficacy of neuroprostheses.

One in Ten Pregnant People Who Contract COVID Will Develop Long COVID

Nearly one in ten people who get COVID while pregnant will go on to develop long COVID, a new report has found.

Type 1 Diabetes Leaves Distinct T-Cell Signatures in the Blood

A study has found distinct signatures in T cells in blood samples from children with newly diagnosed type 1 diabetes. These T-cell signatures could be used to develop better biomarkers for evaluating type 1 diabetes risk.

Discovery of a New Enzyme Could Contribute to Novel Antibacterial Therapies

A bacteriophage-derived enzyme called endolysin is capable of targeting biofilms formed by Enterococcus faecalis, contributing to novel antibacterial therapies.

Liver Cells Put a “Sleep Timer” On Immune Cells in Chronic Hepatitis B Infection

A team has discovered that cells in blood vessels in the liver start a “sleep timer” that switches off immune cells, and targeting this mechanism could be a starting point for immunotherapies.

Cell-Based Lymphoma Therapy Shows Promise in Trial

CAR-T cell therapy causes tumors to shrink or disappear, but if this CAR-T treatment fails, the median survival time after relapse is about six months. Now, a phase 1 clinical trial has found that a new CAR-T cell therapy significantly improved these patients’ outcomes.

Researchers Create Novel Cell Type That Kills Cancer Cells in Research Models

Researchers have combined the genetic components of four types of cells to make a powerful new cell type, Co-STAR (Co-stimulatory Synthetic T-cell receptor and Antigen Receptor) cells. These cells were able to produce a sustained anti-tumor response against human cancer cells in laboratory studies.

Researchers Discover an Immune Defect in Lupus and a Possible Way To Reverse It

Researchers have uncovered a molecular defect that promotes the pathologic immune response in lupus, and have shown that reversing this defect could treat the disease.

Liver Tumor Microproteins Could Lead to Cancer Vaccines

A study has identified a group of small molecules that could be key to developing cancer vaccines. These microproteins are very small proteins expressed only by tumor cells and can activate immune cells against the tumor.

Hepatitis C Leaves Lasting “Scars” On the Immune System Even After Treatment

New research has provided insights into the lasting effects of chronic Hepatitis C virus (HCV) infection on the immune system.
