B cells

[Nature Reviews Rheumatology] The authors describe the importance of lymphocyte-stromal cell interactions in chronic inflammation, with a focus on human disease, using three selected autoimmune and inflammatory diseases.

[Nature Communications] Scientists reported SARS-CoV-2 specific T cell responses in infected adults and children and find that the acute and memory CD4+ T cell responses to structural SARS-CoV-2 proteins increase with age, whereas CD8+ T cell responses increase with time post-infection.

[Cell Death Discovery] The authors screened compounds inhibiting breast cancer cell proliferation with hematopoietic PBX-interacting protein (HPIP) fused with green fluorescent protein as a reporter. A novel agent named TXX-1-10 derived from rimonabant was discovered to reduce HPIP expression and had greater inhibitory effects on breast cancer cell growth and metastasis in vitro and in vivo than rimonabant.

[Science Immunology] Scientists demonstrated that the loss of Pax5 by conditional mutagenesis in peripheral B lymphocytes led to the strong reduction of B-1a, marginal zone and germinal center B cells as well as plasma cells.

[Journal of Investigative Dermatology] Increased autoantigen presentation by HLA molecules, cross-activation of pathogen-induced T cells against autologous structures, altered metabolism of self-proteins, and excessive production of proinflammatory signals may all contribute to the breakdown of immune tolerance and the development of autoimmune skin diseases.

[Bone Marrow Transplantation] Investigators evaluated the immune reconstitution of patients receiving omidubicel grafts during the first six months post-transplant, as IR is critical for favorable outcomes of the procedure.
