Newer COVID-19 Subvariants Are Less Vulnerable to Immunity Induced by Vaccination and Previous Infection, Researchers Find

In a letter published in the New England Journal of Medicine, physician-scientists report that the three Omicron subvariants currently dominant in the United States – officially known as subvariants BA.2.12.1, BA.4, and BA.5 – substantially escape neutralizing antibodies induced by both vaccination and previous infection.

Phase separation found in immune response within cells

Protein complexes that play a critical role in launching an immune response assemble in droplets that form within the liquid environment in cells much like oil droplets in water, UT Southwestern scientists report in a new study. The findings, published in Molecular Cell, could lead to new interventions to regulate immunity in individuals with overactive or underactive immune responses.

Strong immune response underlies acute kidney injury related to COVID-19

Mayo Clinic researchers have found that acute kidney injury associated with COVID-19 resembles sepsis-caused kidney injury, and the immune response triggered by the infection plays a pivotal role.

The findings, published in Mayo Clinic Proceedings, also suggest that mitochondrial dysfunction — a loss of function in cellular energy production — is commonly found in kidney injury related to COVID-19.

Researchers Discover Mechanism to Overcome Drug-Resistance in B-Cell Acute Lymphoblastic Leukemia

In a new study led by Yale Cancer Center, researchers have discovered a novel metabolic gatekeeper mechanism for leukemia. This mechanism depends on a molecule called PON2, which could lead to a new treatment for the disease. The findings were published online today in the Proceedings of the National Academy of Sciences.

The Gut Microbiome, CRISPR/Cas-9, and More Featured in August 2020 Toxicological Sciences

The August 2020 issue of Toxicological Sciences includes exciting advances in toxicology research. The edition features pieces on biotransformation, toxicokinetics, and pharmacokinetics; developmental and reproductive toxicology; and more.

Researchers Receive NIH Funds for Adjuvant Research to Boost Coronavirus Vaccines

Researchers have received funding from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, to screen and evaluate certain molecules known as adjuvants that may improve the ability of coronavirus vaccines to stimulate the immune system and generate appropriate responses necessary to protect the general population against the virus.

Natural Toxins in the Global Food Supply Continue to Threaten the Health of Underprivileged Communities

Naturally occurring chemicals in the global food supply are known to pose a burden on worldwide health. New studies have found that a certain foodborne toxin, in addition to its known health effects,, is also linked to vaccine resistance, and for the first time the global burden of disease from foodborne arsenic, lead, cadmium, and methyl mercury has been quantified.. The Society for Risk Analysis (SRA) will present new studies as part of its Global Disease Burden Caused by Foodborne Chemicals and Toxins symposium on Monday, Dec. 9 from 1:30-3:00 p.m. as part of its 2019 Annual Meeting at the Crystal Gateway Marriott in Arlington, Virginia. This symposium will provide updates to a 2015 World Health Organization (WHO) publication which analyzed the disease burdens caused by these toxins.
