Induction of cross-reactive antibody responses against the RBD domain of the spike protein of SARS-CoV-2 by commensal microbiota

This study identifies commensal bacteria that induce cross-reactive anti-RBD IgA antibodies against SARS-CoV-2 in humans and mice.

Mobilization of tissue-resident memory CD4+ T lymphocytes and their contribution to a systemic secondary immune reaction

The paper shows that tissue-resident memory CD4+ T cells mobilize into the blood after vaccination and contribute to systemic secondary immune responses.

Antigen-driven PD1+Tox+Eomes+ and PD1+Tox+BHLHE40+ synovial T lymphocytes regulate chronic inflammation in situ

The paper identifies distinct subpopulations of synovial T lymphocytes in JIA patients using single-cell RNA-sequencing and shows their roles in regulating chronic inflammation.

Stromal cell-contact dependent PI3K and APRIL induced NF-κB signaling complement each other to prevent mitochondrial- and endoplasmic reticulum stress induced cell death of bone marrow plasma cells

The paper shows that stromal cell contact and APRIL signaling via PI3K and NF-κB pathways prevent mitochondrial and ER stress-induced apoptosis in bone marrow plasma cells.

Discrete populations of isotype-switched memory B lymphocytes are maintained in murine spleen and bone marrow

The paper identifies discrete populations of isotype-switched memory B cells in murine spleen and bone marrow, with distinct locations and characteristics.
