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.

Adults' exposure to diverse microbes may worsen allergic conditions

The "hygiene hypothesis" suggests exposure to diverse types of microbes may protect against developing diseases caused by allergens, but a new Cornell University study in mice reveals that adults' exposure to diverse microbes and allergens may in fact worsen certain allergic conditions.

Armored CAR T cells overcome tumor defenses in solid cancers

UCLA scientists have developed a next-generation CAR-T cell therapy that can overcome the immunosuppressive tumor microenvironment, a protective shield that tumors use to weaken immune cells, block their attack and fuel tumor growth.

Natural fungal supplement strengthens vaccine protection without increasing side effects

Researchers at University California San Diego School of Medicine have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies - the body's natural immune defenders - last longer in people who had not previously been exposed to the virus.

Gut bacteria may explain differences in peanut allergy reactions

One of the big mysteries in food allergy is why two people with similar levels of peanut specific antibodies can react so differently. It turns out the answer may be in the mouth and gut's bacteria.

New collaboration explores familial inflammatory bowel disease in Saudi Arabia

Mount Sinai and King Saud University Medical City in Riyadh, Saudi Arabia, today announced a three-year collaboration aimed at better understanding why inflammatory bowel disease (IBD) runs in some Saudi families, and how that knowledge can lead to risk ascertainment, earlier diagnosis and more personalized treatment options.

New research initiative aims to predict and prevent diseases before they start

What if doctors could tell you a disease was coming years before you felt a single symptom-and stop it in its tracks? That is the goal of a sweeping new research initiative launched by the Icahn School of Medicine at Mount Sinai in collaboration with the Uniformed Services University of the Health Sciences (USU) and the Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF).

MERLIN algorithm unlocks immune cell location memory in organs

A new AI-based method reconstructs spatial information about where immune cells were originally located in an organ, even after these cells have been removed from the tissue and analyzed individually.

Targeted PET/CT tracer improves early prediction of treatment response in rheumatoid arthritis patients

A new targeted PET/CT tracer can detect treatment response in rheumatoid arthritis patients in as little as four weeks, and potentially even at the start of treatment, according to new research published in The Journal of Nuclear Medicine.

New structural insights pave way for hantavirus vaccines

Hantaviruses, transmitted from rodents to people, have a death rate approaching 40%. They're found around the world, and because there are no approved vaccines or treatments, they're among the pathogens of highest concern for future pandemics.

Protein partnership enhances innate immune sensing of viral RNA

Study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science Tokyo.

Immune cells shape maternal and infant health during lactation

It's widely known that breastfeeding impacts the health of both mother and child, but the underlying biology that leads to these effects has been understudied.

Combination therapy may help overcome barrier in early-stage prostate cancer treatment

A multi-institutional study led by Mayo Clinic and published in Cell Reports Medicine reports that pairing a next-generation immunotherapy with standard hormone therapy before surgery may help overcome a long-standing barrier in early-stage prostate cancer treatment.

Scientists uncover key protein essential for malaria parasite survival

An international team of scientists has shed light on the development of the malaria parasite and have identified a unique protein essential for its survival and transmission, which offers a promising new target for antimalaria drugs.

RSV and COVID-19 trigger different immune responses in infants

Young infants hospitalized with respiratory syncytial virus (RSV) often become much sicker compared to those infected with SARS-CoV-2, the virus that causes COVID-19.

Disrupted lymphatic vessels may drive chronic organ transplant rejection

Despite advances in the field of organ transplantation, long-term organ rejection that can become apparent a decade or more after a heart or lung transplant remains a common problem for patients.

Early-life immune system differences drive childhood eczema risk

A team of researchers at the Icahn School of Medicine at Mount Sinai, Weill Cornell Medicine, and other institutions have uncovered a key biological explanation for why eczema so often starts in childhood.

Unexpected behavior observed during interactions between immune cells and dying cells

Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm by a robust nuclear envelope.

Lingering brain inflammation found after mild COVID infection

Even a mild case of COVID-19 or the flu can impact the body long after the fever and cough fade, according to new Tulane University research that may help explain why some people struggle to feel fully recovered weeks or months later.

Researchers uncover vulnerabilities in elusive HIV reservoir clones

A new study has overcome a long-standing challenge-how to isolate and study elusive HIV-infected cells called authentic reservoir clones (ARCs) that evade the immune system, making the disease difficult to cure.
