Downregulation of MHC-I surface expression by SARS-CoV-2 accessory proteins

Researchers analyze the mechanisms by which two SARS-CoV-2 accessory proteins, ORF3a and ORF7a, can downregulate the expression of MHC-I.

Researchers explore SARS-CoV-2 infection in lung myeloid cells

Scientists discuss how SARS-CoV-2 utilizes myeloid cells to allow for the subsequent viral colonization in the lungs.

Impact of COVID-19 second booster vaccine on all-cause death among older cohorts

Scientists illustrated that the second booster dose of the SARS-CoV-2 vaccinations lowered all-cause death in the long-term care home residents and those aged 80 years or older.

Immunity conferred by COVID-19 vaccines in solid organ transplant recipients

In a recent study posted to the medRxiv* preprint server, researchers estimated the humoral immunity imparted by the two/three doses of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in solid organ transplant recipients (SOTRs).

RGS2 protein expression may explain reduced sense of smell in COVID

Researchers tested the hypothesis that anosmia in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals elevates the expression of the odorant receptor, a regulator of G protein signaling 2 (RGS2) in humans.

Recombinant protein vaccine stands up to SARS-CoV-2 variants

A study by researchers in Texas describes a mouse model in which a subunit vaccine with alum-CpG adjuvant was tested for its ability to induce a broadly neutralizing antibody response against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Tabula sapiens, most comprehensive human cell atlas

In a recent study published in the journal Science, researchers created an atlas termed the Tabula sapiens for over 400 distinct cell types of humans. Several aspects of human physiology were revealed by the atlas, such as how different types of cells splice genes differently.
