Researchers showed that human papillomavirus (HPV)-specific B cell responses were detectable in samples from patients with HPV-positive head and neck cancers, with active production of HPV-specific IgG antibodies in situ.
Investigators discovered that scutellarin suppressed inflammation and epithelial–mesenchymal transition in BLM-induced pulmonary fibrosis through NF-κB/NLRP3 signaling.

This study was designed to test the hypothesis that proprotein convertase subtilisin/Kexin type 9 (PCSK9) regulates pyroptosis in cardiomyocytes during chronic myocardial ischemia. Primary cardiomyocytes were isolated from WT and PCSK9−/− mice.

Investigators addressed the therapeutic efficacy of human adipose tissue stem cells derived extracellular vesicles in a mouse model of dry eye disease and to investigate the underlying mechanisms involved.
When adipose-derived stromal/stem cells (ASC) spheroid cultured in 3D were compared with ASCs cultured in 2D monolayer, the cell survival and chondrogenic potential were enhanced while the apoptosis was reduced in ASC spheroids.

Scientists investigated B cell fate programming and heterogeneity during anti-body secreting cells (ASCs) differentiation using T cell-independent models. They found that maximal ASC induction required at least eight cell divisions in vivo, with BLIMP-1 being required for differentiation at division eight.
