Four months after launching the nation’s largest COVID-19 serological testing assessment, Texas CARES, researchers at The University of Texas Health Science Center at Houston (UTHealth) and the Texas Department of State Health Services (DSHS) have compiled preliminary data estimating that 14% to 24% of Texans have COVID-19 antibodies.
Nick Pullen, Ph.D., an associate professor of Biological Sciences at the University of Northern Colorado, shares his expertise on the COVID-19 vaccines and debunks some of the myths surrounding them.
Scientists at Washington University School of Medicine in St. Louis have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).
The body's immune response plays a crucial role in the course of a SARS-CoV-2 infection.
The March 2021 issue of Toxicological Sciences includes exciting toxicology research in biotransformation, toxicokinetics, and pharmacokinetics; genetic and epigenetic toxicology; neurotoxicology; and more.
At the beginning of an immune response, a molecule known to mobilize immune cells into the bloodstream, where they home in on infection sites, rapidly shifts position, a new study shows. Researchers say this indirectly amplifies the attack on foreign microbes or the body’s own tissues.
Lymph nodes in the armpit area can become swollen after a COVID-19 vaccination, and this is a normal reaction that typically goes away with time.
By analyzing blood samples from individuals infected with SARS-CoV-2, researchers in Singapore have begun to unpack the different responses by the body’s T cells that determine whether or not an individual develops COVID-19. The study, published today in the Journal of Experimental Medicine (JEM), suggests that clearing the virus without developing symptoms requires T cells to mount an efficient immune response that produces a careful balance of pro- and anti-inflammatory molecules.
Discovery of a metabolic pathways that inhibit memory T cell production has potential for enhancing the immune system’s ability to fight infections and cancers.
Medical researchers have long understood that a pregnant mother’s diet has a profound impact on her developing fetus’s immune system and that babies — especially those born prematurely — who are fed breast milk have a more robust ability to fight disease, suggesting that even after childbirth, a mother’s diet matters. However, the biological mechanisms underlying these connections have remained unclear.
ROCKVILLE, MD – The Zika outbreak of 2015 and 2016 is having lasting impacts on children whose mothers became infected with the virus while they were pregnant.
St. Jude Children’s Research Hospital has discovered a mechanism that tumors use to switch on protective regulatory T cells, raising the potential for drug treatments that render tumors more vulnerable to cancer immunotherapy.
Scientists at the Children’s Medical Center Research Institute at UT Southwestern (CRI) have identified the specialized environment, known as a niche, in the bone marrow where new bone and immune cells are produced. The study, published in Nature, also shows that movement-induced stimulation is required for the maintenance of this niche, as well as the bone and immune-forming cells that it contains. Together, these findings identify a new way that exercise strengthens bones and immune function.
HSE University researchers have become the first in the world to discover genetic predisposition to severe COVID-19. The results of the study were published in the journal Frontiers in Immunology.
La Jolla Institute for Immunology (LJI), one of the leading research organizations dedicated to studying the immune system announced today that it has signed a licensing agreement with Leinco Technologies, Inc., a premier developer and manufacturer of leading-edge recombinant proteins, antibodies, and conjugates.
In patients with severe COVID-19, the innate immune system overreacts.
The course and severity of COVID-19 in individual patients is largely influenced by the interaction between the SARS-CoV-2 coronavirus and the human immune system.
Creating “super soldiers” of specific white blood cells to boost an anti-tumour response has been shown in a series of elegant experiments by Princess Margaret researchers.
A child’s first influenza infection shapes their immunity to future airborne flu viruses – including emerging pandemic strains. But not all flu strains spur the same initial immune defense, according to new findings published today by University of Pittsburgh virologists.
