Diesel exhaust particles disrupt the function of brain's immune cells, study shows

Diesel exhaust particles can disturb the function of human brain immune cells, known as microglia, according to a recent study led by the University of Eastern Finland. The findings, published in Environment International, shed light on how traffic-related air pollution could contribute to brain inflammation and neurodegenerative diseases.

With age the immune system becomes weaker making the body more vulnerable to infections, partly since the body produces fewer and weaker T cells. In experiments with mice, now researchers managed to temporarily boost the production of T cells by using mRNA technology. See http://www.neat-news.com/3492.php. #TCell #mRNA #immune

A 62-year-old man in Germany deliberately got himself 217 doses of #COVID-19 #vaccines 💉 over 29 months. ¿What happened to him?
NOTHING 😐 No notable side effects and a robust #immune response.
That said, the researchers emphasize that they do NOT recommend hypervaccination...

A single signaling pathway controls whether #immune cells attack or befriend cells they encounter while patrolling our bodies, researchers at Stanford Medicine have found. Manipulating this pathway could allow researchers to toggle the immune response to treat many types of diseases, including cancers, autoimmune disorders and those that require organ transplants.

The yeast Candida albicans colonizes mucosal surfaces and is usually harmless. However, under certain conditions it can cause dangerous infections. A research team at the University of Zurich has now discovered how the #immune system prevents the transformation from a harmless colonizer to a #pathogenic mode.

We have the innate immune system, and we have the adaptive immune system, which we have known how to give hints and references, and encourage, for a century and a half, and now we are heading toward an overlay of direct instructions to immune components, an engineered immune system. But there is probably a better name for that upper layer.

Don't give your pet mouse 🐁️ a tattoo. A study by Capucetti et al. in PNAS found the ink lingers in lymph nodes for months and kills immune cells. Effect on vaccines varied; Comirnaty (for COVID) injected into a tattoo was weaker while the flu jab was stronger.
