Mild cases of coronavirus disease 2019 (COVID-19) can trigger robust memory T cell responses, even in the absence of detectable virus-specific antibody responses, researchers report.
Bacteria’s secret weapon revealed
Scientists have discovered a previously unknown method used by bacteria to evade immune responses.
Naturally occurring antibodies against prion proteins found in humans
Antibodies targeting the normal PrP version of the prion protein have been found in humans selected at random with no history of any associated transmissible spongiform encephalopathies. Researchers report on active antibodies against PrP at high level…
Negative side effects of opioids could be coming from users’ own immune systems
In addition to possibly developing opioid use disorder, those who take opioids long term can develop chronic inflammation and heightened pain sensitivity. Scientists now report that some of those side effects might be influenced by the body’s own immun…
Immunotherapy extends survival in mouse model of hard-to-treat breast cancer
Immunotherapies for cancer — treatments that prime the immune system to attack tumors — are valuable weapons in the anti-cancer arsenal. But some cancers are more difficult to target with this strategy than others. Today, scientists report a new immu…
Immune response to Sars-Cov-2 following organ transplantation
Even patients with suppressed immune systems can achieve a strong immune response to Sars-Cov-2. A test helps to adapt therapy following an infection.
Pregnant mother’s immunity tied to behavioral, emotional challenges for kids with autism
Children with autism born to mothers who had immune conditions during their pregnancy are more likely to have behavioral and emotional problems, a new study has found. Offspring sex may also interact with maternal immune conditions to influence outcome…
Study explores the association of malaria, HIV with anemia during pregnancy
Pregnant women from sub-Saharan Africa with malaria and human immunodeficiency virus (HIV) have a higher prevalence of anemia than pregnant women without infections, according to researchers. The findings may have implications for reducing the risk of …
Researchers discover the microbiome’s role in attacking cancerous tumors
Researchers have discovered which gut bacteria help our immune system battle cancerous tumors and how they do it. The discovery may provide a new understanding of why immunotherapy, a treatment for cancer that helps amplify immune response, works in so…
Seasonal flu vaccinations don’t ‘stick’ long-term in bone marrow
Seasonal flu vaccination does increase the number of antibody-producing cells specific for flu in the bone marrow. However, most of the newly generated cells are lost within one year, researchers found.
