Medical researchers have shown that optimizing the energy metabolism of key cells enables people with HIV-1 to better defend themselves against the virus.
Immune system keeps the intestinal flora in balance
Trillions of benign bacteria live in the intestine. They are kept in a continuous balance by the immune system, which thereby makes them harmless to humans. Researchers have been able to show how certain natural antibodies keep these bacteria in check….
Scientists develop new strategy that rapidly quantifies transmissibility of COVID-19 variants
Researchers have developed a new nanomechanical technique for fast, one-step, immune-affinity tests, which can quantify the immune response induced by different COVID-19 variants in serum. Their technique provides a new tool for tracking infection immu…
How immunotherapy changes tumors
Engineers have used a non-invasive optical probe to understand the complex changes in tumors after immunotherapy, a treatment that harnesses the immune system to fight cancer. Their method combines detailed mapping of the biochemical composition of tum…
Scientists discover a highly potent antibody against SARS-CoV-2
Scientists have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date, including the delta variant.
Sex matters when it comes to immune responses against infection and disease, study shows
New research shows how anemia can generate different immune responses in males versus females.
Common respiratory virus manipulates immune genes to protect itself
Researchers have discovered that the viral protein NS1 from respiratory syncytial virus (RSV) alters the activity of immune genes, sabotaging the immune response to RSV infection.
Break through the tumor’s protective shield
The immune system protects the body from cancer. To protect healthy body cells from its own immune system, they have developed a protective shield: the protein CD47 is a so called ‘don’t eat me’ signal, which tells the immune cells to stand back. Tumor…
New avenues for the optimzation of dendritic cell-based cancer immunotherapies
A recent study reveals that inhibiting certain adhesion receptors on the surface of dendritic cells, the main antigen-presenting cells of the immune system, enhances antitumor responses.
Link between COVID vaccination and reduced household transmission, Swedish study finds
People without immunity against COVID-19 were at considerably lower risk of infection and hospitalization as the number of family members with immunity from a previous infection or full vaccination increased, according to a new study from Sweden.
