Convalescent plasma shows CD8+ T cell responses to SARS-CoV-2 variants

Researchers in the United States have conducted a study suggesting that individuals who have recovered from or been vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) should maintain effective CD8+ T-cell responses against the major variants that have recently emerged.

Blood-clotting protein linked with tumor pathogenesis of CNS B-cell lymphoma

In people with central nervous system (CNS) lymphoma, cancerous B cells--a type of white blood cell--accumulate to form tumors in the brain or spinal cord, often in close proximity to blood vessels.

New N501Y SARS-CoV-2 mutations increase binding to host cell receptor

A team of researchers used several assays, atomic force microscopy, and simulations to determine that the N501Y mutation in the virus’s receptor-binding domain (RBD) increased the interaction of the virus with the angiotensin-converting enzyme 2 (ACE2) receptor.
