Researchers on the University of Wisconsin–Madison have identified a protein key to the event of a sort of brain cell believed to play a task in disorders like Alzheimer’s and Parkinson’s diseases and used the invention to grow the neurons from stem cells for the primary time. The stem-cell-derived norepinephrine neurons of the kind present […]
There is no doubt that exercise does a body good, including strengthening and toning our muscles. But how exactly does exercise make this occur? As we run and lift and stretch, our muscles experience chemical signals from surrounding cells, in addition to mechanical forces from jostling against tissues. Some physiologists wonder: Is it the body’s […]
Imagine the lifetime of a yeast cell, floating across the kitchen in a spore that eventually lands on a bowl of grapes. Life is sweet: food for days, not less than until someone notices the rotting fruit and throws them out. But then the sun shines through a window, the section of the counter where […]
Red blood cells exposed to oxygen deficiency protect against myocardial infarction, in line with a brand new KI study published within the Journal of Clinical Investigations. The study also shows that the protective effect is enhanced by a nitrate-rich vegetable food plan. Red blood cells carry oxygen from the lungs to the entire body’s cells […]
A brand new study led by researchers at Karolinska Institutet in Sweden has examined how T cells of the immune system are affected by weightlessness. The outcomes, that are published within the journal Science Advances, could explain why astronauts’ T cells change into less energetic and fewer effective at fighting infection. The subsequent steps within […]
Ziya Isiksacan, PhD, a research fellow within the Center for Engineering in Medicine and Surgery (CEMS) is the lead creator, and Osman Berk Usta, PhD, an investigator within the CEMS at Massachusetts General Hospital and an associate professor of Surgery at Harvard Medical School, is the senior creator of a brand new study published in […]
As a part of the immune system, dendritic cells are essential for fighting body cells which have degenerated or are infected with a virus. They trigger an immune response by presenting protein fragments, for instance of viruses, to T cells. In so doing, they activate the latter in order that these recognize the fragments as […]
In a recent study published within the Nature Aging Journal, researchers investigated the role of senescent cells within the context of SARS-CoV-2 infection. Study: Removal of senescent cells reduces the viral load and attenuates pulmonary and systemic inflammation in SARS-CoV-2-infected, aged hamsters.

Type 1 diabetes (T1D) is an autoimmune disease linked to helper T-cell recognition in non-obese diabetic (NOD) mice and humans. Furthermore, T1D affects the endocrine pancreas, thus causing patients to be depending on insulin alternative therapy for the remaining of their lives. Monitoring disease progression through peripheral blood sampling could provide insights into the immune-mediated […]
Evidence is mounting that astronauts are more vulnerable to infections while in space. For instance, astronauts on board the International Space Station (ISS) commonly suffer from skin rashes, in addition to respiratory and non-respiratory diseases. Astronauts are also known to shed more live virus particles, for instance Epstein-Barr virus, varicella-zoster chargeable for shingles, herpes-simplex-1 chargeable […]
