B cells and their function in the immune system

Whenever a germ gets into the human body, the immune system usually responds immediately to fight off the enemy attacker. One of our defense system’s most important strategies involves B lymphocytes, also known as B cells, which produce antibodies that target and neutralize pathogens. B cells play a central role in adaptive immunity and, together […]

Pfizer's coronavirus shot shows promise by triggering immune response

Experimental coronavirus vaccine from Pfizer triggered levels of antibodies up to THREE TIMES greater than those seen in recovered patients, early data shows Researchers randomly gave 45 healthy volunteers either a low dose, a medium dose or a high dose of a coronavirus vaccine, or a placebo Those who received the vaccine were given two shots, except […]

Engineered immune cells recognize, attack human and mouse solid-tumor cancer cells

A method known as CAR-T therapy has been used successfully in patients with blood cancers such as lymphoma and leukemia. It modifies a patient’s own T-cells by adding a piece of an antibody that recognizes unique features on the surface of cancer cells. In a new study, researchers report that they have dramatically broadened the […]

Study shows nervous and immune systems ‘need to talk’ for bone repair

In a December 2019 study, a team of Johns Hopkins Medicine researchers demonstrated in mice that repair of bone fractures requires the generation, growth and spread of nerve cells, or neurons, throughout the injured area. This, they showed, partly relies on a protein known as nerve growth factor (NGF). Now, the researchers have dug deeper […]

Scientists uncover immune cells that may lower airway allergy and asthma risk

The world is full of house dust mites. Do some cleaning, and you’ll probably stir some up. While everyone has immune cells capable of reacting to common allergens like house dust mites, most of us have no allergic symptoms. Still, many people do react with the typical allergic symptoms: sneezing, a runny nose, and itchy, […]

Microbiome rewilding: Biodiverse urban green spaces strengthen human immune systems

A research team led by the University of Adelaide has found that revegetation of green spaces within cities can improve soil microbiota diversity towards a more natural, biodiverse state, which has been linked to human health benefits. In the study, published in the journal Restoration Ecology, researchers compared the composition of a variety of urban […]

New study shows how immune surveillance system is triggered within tissues

White blood cells are known to circulate through the entire body through blood vessels, acting as a surveillance system. However, a specialized group of these cells are permanently present in tissues like the skin, intestine and lungs, protecting against external invaders such as microbes. But it is largely unknown how these cells are generated. A […]

Can you ‘boost’ your immune system against COVID-19?

As we continue our collective battle against the novel coronavirus (COVID-19), you may have come across various claims of foods or supplements that supposedly increase your immunity against the disease. Here, we break down some basic facts about how nutrition plays into having a healthy immune system. “Boosting” the Immune System First, there are no […]

SARS-CoV-2 may be exploiting our immune system’s ‘first responder’ cells

The new coronavirus, known as SARS-CoV-2, may be using part of the human body’s own immune response against us, a new study suggests. The novel coronavirus is known to use a keyhole called the ACE2 receptor to “unlock” a cell and get inside, where it replicates and wreaks havoc. Now, researchers have found that the […]
