Study reveals sex-dimorphic immune imprints and in vivo functional impacts of mild COVID-19

Researchers used a systems immunology approach to analyze the immune states of healthy and non-obese subjects who recovered from mild COVID-19 and compared them with age- and sex-matched COVID-19-naive controls.

Genetics may influence how the body responds to vaccines and boosters

Genetics play an important role in how our bodies respond to vaccines and booster shots, suggesting that certain protective responses elicited by vaccination could be more effective with personalization, according to a new study led by University of Michigan researchers.

Circulating miR-155 may predict chances of survival in hospitalized COVID-19 patients

Scientists from Israel have recently estimated the levels of circulating microRNAs (miRNAs) in hospitalized coronavirus disease 2019 (COVID-19) patients with the aim of identifying prognostic biomarkers for disease severity. They have identified miR-155, an important regulatory molecule in the immune system, as a potential biomarker to predict COVID-19 severity and mortality.

Study shows Pfizer-BioNTech booster protects over 65s against Delta and Omicron

New research in nursing home residents found that a third dose of the Pfizer-BioNTech COVID-19 vaccine was effective for at least three months in protecting against the Delta and Omicron variant. While two doses of an mRNA COVID-19 vaccine showed poor neutralization to Omicron than Delta, a booster shot increased neutralizing antibody responses.

Scientists use entire human GI tracts to shed light on cellular functions

If you get nervous, you might feel it in your gut. If you eat chili, your gut might revolt, but your friend can eat anything and feel great. You can pop ibuprofen like candy with no ill effects, but your friend's belly might bleed and she might get no pain relief.
