Immunology

Immunology is the study of the body's immune system.

What is Immunology?

Immunology is the branch of biomedical science that deals with the response of an organism to antigenic challenge and its recognition of what is self and what is not. It deals with the defence mechanisms including all physical, chemical and biological properties of the organism that help it to combat its susceptibility to foreign organisms, material, etc.

Artificial sweetener may undermine effectiveness of cancer treatment

Sucralose is a popular sugar substitute for people who are cutting calories or managing blood sugar levels, but new research by the University of Pittsburgh and UPMC Hillman Cancer Center suggests that the artificial sweetener may not be the best choice for patients undergoing cancer immunotherapy.

Updated guideline aims to identify quality improvement opportunities in managing adult sinusitis

The American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) published the Clinical Practice Guideline (CPG): Adult Sinusitis Update today in Otolaryngology–Head and Neck Surgery.

T cell senescence shapes cancer prognosis and immunotherapy response

T cell senescence occurs in the TME, affecting cancer prognosis and immunotherapy efficacy. The TME induces T cell senescence through multiple pathways, including persistent stimulation by tumor-associated antigens, metabolic pathway alterations, activation of chronic inflammatory responses, proliferation of immunosuppressive cells, and T cell damage caused by tumor radiotherapy and chemotherapy.

Respiratory infections can reactivate dormant breast cancer cells

Researchers at the University of Colorado Anschutz Medical Campus, Montefiore Einstein Comprehensive Cancer Center (MECCC), and Utrecht University have found the first direct evidence that common respiratory infections, including COVID-19 and influenza, can awaken dormant breast cancer cells that have spread to the lungs, setting the stage for new metastatic tumors.

Single injection of gene therapy at birth may offer lasting protection against HIV

A new study in Nature shows that delivering a single injection of gene therapy at birth may offer years-long protection against HIV, tapping into a critical window in early life that could reshape the fight against pediatric infections in high-risk regions.

New insights reveal how Candida albicans settle and persist in the gut

About 80% of people have the fungus Candida albicans in their gut. Although most of the time it persists unnoticed for years causing no health problems, C. albicans can turn into a dangerous microbe that causes serious diseases in many organs, including the urinary tract, lungs and brain.

Intratumoral microbial metabolites shape the tumor microenvironment and impact immunotherapy

The tumor microenvironment (TME) represents a highly complex system that encompasses cellular components (such as cancer cells, stromal cells, and immune cells) and non-cellular components (such as blood vessels and signaling molecules).

PD-1 helps guide immune memory cells to the skin early during infection

Weill Cornell Medicine researchers have discovered that PD-1—a molecule best known for putting the brakes on immune cells—also plays a critical role in helping T cells become long-term immune defenders in the skin.
