Study shows how two distinct groups of Tregs play different roles at different times

Every kind of T cell has a job to do. A healthy immune system makes sure no T cell oversteps.

New vaccine providing protection against future animal-to-human viral diseases may be possible

A future vaccine providing protection against a wide range of coronaviruses that jump from their original animal hosts to humans -; including SARS-CoV-2, the cause of COVID-19 -; may be possible, say Johns Hopkins Medicine researchers, based on findings from their recent study.

COVID-19 vaccines prompt the body to make long-lasting T cells against different variants

Scientists at La Jolla Institute for Immunology (LJI) have found that four COVID-19 vaccines (Pfizer-BioNTech, Moderna, J&J/Janssen, and Novavax) prompt the body to make effective, long-lasting T cells against SARS-CoV-2.

Covid-19 vaccine-elicited immune cells persist six months after vaccination, study shows

A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes — immune system cells also known as helper T cells — produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at significantly higher levels than for those who are unvaccinated.

Researchers discover underlying metabolic changes that may be pivotal in severe COVID-19

COVID-19 patients have differing immune responses that lead to disease outcomes ranging from asymptomatic SARS-CoV-2 infection to death.

Warped immune cell signaling during bile acid exposure may lead to Crohn’s disease

People with Crohn's disease are typically treated with powerful anti-inflammatory medications that act throughout their body, not just in their digestive tract, creating the potential for unintended, and often serious, side effects.

Study shows how a subset of T cells is generated in melanoma survivors affected by vitiligo

A few patients suffering from melanoma are known to respond quite well to immunotherapy and experience significant and long-lasting tumor regression.

Protein kinases may offer a solution to treat HIV patients with immunodeficiency

A new study indicates that protein kinases, which initiate the process that erodes the body’s immunity, significantly contribute to the immunodeficiency in HIV patients. Drugs that block these protein kinases may offer a solution to treating HIV patients whose immunity is not restored by antiretroviral therapy.

Animal model yields important insights into T cell exhaustion

T lymphocytes, or T cells, are an important component of our immune system. They can recognize foreign proteins, so-called antigens, as peptide fragments - for instance, those derived from viruses or cancer cells.

New therapeutic approach to restore the effectiveness of immune cells

Prompted by the need to improve conventional treatments for people infected with the human immunodeficiency virus (HIV-1), a team from the Institut national de la recherche scientifique (INRS) has identified a therapeutic approach to restore the effectiveness of immune cells.
