The rules to the kids' game "red light, green light" are easy to follow: red always means stop, and green always means go. But now, researchers from Japan have found that a key protein involved in B cell signaling acts as both a red light to signaling in healthy cells and a green light to signaling in immune-deficient cells.

A new study analyzed the recall of pre-existent cross-reactive memory B cells upon the SARS-CoV-2 Omicron breakthrough infections.

Researchers reported breakthrough infections by SARS-CoV-2’s new variant of concern, Omicron, that elicited broadly cross-reactive neutralizing antibodies in the BNT162b2-vaccinated individuals.

A new study discovered immunoglobulins with powerful broad-acting neutralizing capacity against SARS-CoV-2 from SARS-CoV-2 convalescents.

Researchers developed a novel high-throughput method to obtain monoclonal antibodies from COVID-19 individuals infected with SARS-CoV-2 ancestral strain Wuhan-Hu-1 and the Beta or Gamma variants.

Scientists have long queried the causes of immune disorders in only one of two identical twins with identical genes. New research from the Wellcome Sanger Institute, the Josep Carreras Leukaemia Research Institute in Spain and their collaborators, has found the answer lies in both alterations in immune cell-cell communication and the epigenome, the host of biological processes that regulate how our genes function.

Researchers raised concerns that some SARS-CoV-2 variants can escape detection by antigen tests.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection incites adaptive cellular immune responses. In many SARS-CoV-2 studies, peripheral blood is analyzed to study the immune responses. Now, a new study under consideration at the Nature Portfolio Journal analyzes the peripheral blood, tonsils, and adenoids of children to understand local and systemic immune responses to SARS-CoV-2.

A recent study finds that there is no considerable B-cell immunity against SARS-CoV-2 in unexposed healthy individuals.

Researchers evaluated the humoral and cellular immune memory induced by four COVID-19 vaccines representing three different vaccine platforms.
