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.

Yale study offers critical clues for future norovirus treatments

As the leading cause of viral gastroenteritis worldwide, norovirus is an all too familiar ailment. Its telltale digestive upset — not to mention its reputation for being notoriously contagious — has earned it the nicknames "winter vomiting bug" and "stomach flu."

Scientists find link between bacterium in the gut ecosystem and lupus

Scientists at UT Health San Antonio, the academic health center of The University of Texas at San Antonio, found a link between a bacterium in the gut microbiome, or ecosystem, and lupus, which could lead to more effective treatment of the disease, in a study published in Nature Communications.

New cell culture method allows targeted study of antibody regulation

For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance.

Chronic stress helps tumors evade immune attack through gut microbes

Chronic psychological stress can help tumors evade immune attack through a chain of molecular events involving gut bacteria and viruses within those bacteria, according to a study led by Weill Cornell Medicine investigators.

Targeting metabolic pathways could prevent relapse in KRAS-mutant cancers

Our cells rely on tightly regulated signaling pathways to control when they grow, divide, and survive. When these regulatory systems are disrupted, cells can acquire the ability to grow uncontrollably and become cancerous.

New biomarkers identify trauma patients at risk for chronic critical illness

New research, published in The Journal of Immunology, identified biomarkers of a distinct immune profile that could be used to identify patients at risk for chronic critical illness (CCI) upon admittance to the intensive-care unit (ICU) after traumatic injury.

Scientists identify genes linking air pollution to severe asthma

For many people with asthma, air-quality advisories are harbingers of worsening symptoms. But for reasons science has struggled to explain, the extent to which pollution exacerbates asthma varies widely from person to person.

Study reveals early immune clues to predict active tuberculosis risk

An early view of the immune response to bacteria in the lungs provides clues as to why some people keep TB in check, while others develop disease, suggesting new ways to intervene earlier and stop TB.

New TRUECAM wrapper makes medical artificial intelligence more trustworthy

Medical artificial intelligence (AI) faces a fundamental challenge: uncertainty quantification. Artificial neural networks are largely unaware of the limits of their training data and can become overconfident when confronted with unfamiliar inputs. Suppose you train a neural network to distinguish among African mammals.
