Immune system’s killer T cells make mistakes in distinguishing healthy from infectious cell

When it comes to differentiating between a healthy cell and an infectious cell that has to be killed, the immune system’s killer T cells might make mistakes.

Study finds unique molecular mechanism by which Hepatitis C virus evades host’s immune system

Hepatitis C virus (HCV) can cause chronic liver infection, which can lead to irreparable liver damage and liver cancer.

New method helps tests large groups for SARS-CoV-2 infection

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Study shows that Bubonic Plague had a long-term impact on immune gene expression

A new study shows that the Bubonic Plague has had a long-term impact on immune gene expression.

Study suggests that bubonic plague had long-term impact on human immune genes

Scientists examining the remains of 36 bubonic plague victims from a 16th century mass grave in Germany have found the first evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.

Study shows how T cells detect dangerous invaders in the human body

T-cells are known to play a crucial role in the human immune system.

Small molecular changes can have dramatic impact on the CAR T cell function

When researchers from Penn Medicine found that many patients with B-cell acute lymphoblastic leukemia (ALL) treated with the investigational chimeric antigen receptor (CAR) T cell therapy targeting the CD22 antigen didn't respond, they went back to the drawing board to determine why.

Study finds raised levels of specific immune cells in asymptomatic people with COVID-19

The largest study of its type in the UK has identified differences in the immune response to COVID-19, between people with no symptoms, compared to those suffering a more serious reaction to the virus.

New breakthrough in understanding the role of high-risk immune genes in rheumatoid arthritis

Researchers within the Biomedicine Discovery Institute at Monash University have made a breakthrough in understanding the role played by high-risk immune genes associated with the development of rheumatoid arthritis (RA).

Study explains molecular mechanisms of drug resistance in Mycobacterium tuberculosis

A group of researchers from France, Germany, Belarus, Japan, and Russia and headed by a scientist from Skolkovo Institute of Science and Technology (Skoltech) has discovered how Mycobacterium tuberculosis survives in iron-deficient environments by using rubredoxin B (RubB)—a protein that belongs to the rubredoxin family and plays a significant role in adapting to varying environmental conditions.

Customized tumor cell vaccine produces active immune response in melanoma, neuroblastoma models

A pre-clinical study for melanoma and neuroblastoma shows that a customized tumor cell vaccine technique that targets Myc oncogenes coupled with checkpoint therapy produces an active immune response that bypasses antigen selection and immune privilege.

Researchers use mathematical modeling to explain CAR T-cell therapy dynamics

Chimeric antigen receptor T-cell therapy, or CAR T, is a relatively new type of therapy approved to treat several types of aggressive B cell leukemias and lymphomas.

Non-circulating memory T cells contribute to chronic transplant rejection

The main function of non-circulating memory T cells is to offer local protection against re-infection.

Study advances CAR T cell therapy targeted at cancer

Cancer immunotherapy involves the activation of cells in the patient’s own immune system to fight tumor cells.

Immune receptor proteins can help treat autoimmune diseases

TARM1 is a receptor protein, whose function in the working of the immune system is not known yet. Now, in a new research work, Japanese researchers have analyzed mouse models to investigate the promising role of TARM1 protein in the pathogenesis of rheumatoid arthritis.

Immune cells in cerebrospinal fluid could be biomarkers to predict immunotherapy response

Results from a study led by Joan Seoane, Director of Preclinical and Translational Research co-program at VHIO and ICREA Professor, show that immune cells accessing cerebrospinal fluid faithfully recapitulate the characteristics of cells identified in brain metastasis, and could therefore constitute novel biomarkers of response to immune-based therapies.

Mutant peptides derived from SARS-CoV-2 hamper activation of CD8+ killer T cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

Engineered safety switch reduces CAR-T immunotherapy-related side effects

UNC Lineberger Comprehensive Cancer Center researchers have successfully used an experimental safety switch, incorporated as part of a chimeric antigen receptor T-cell (CAR-T) therapy, a type of immunotherapy, to reduce the severity of treatment side effects that sometimes occur.
