Temporal Analysis of Brd4 Displacement in the Control of B Cell Survival, Proliferation, and Differentiation

Scientists demonstrated that apoptosis induced by JQ1 was solely attributed to the pro-apoptotic protein Bim. Conversely, cell-cycle regulation by JQ1 was associated with multiple Myc-associated gene targets.

HLA-DR15 Molecules Jointly Shape an Autoreactive T Cell Repertoire in Multiple Sclerosis

Scientists characterized the immunopeptidomes of the two HLA-DR15 allomorphs DR2a and DR2b of human primary B cells and monocytes, thymus, and multiple sclerosis brain tissue.

Polyreactive Broadly Neutralizing B cells Are Selected to Provide Defense against Pandemic Threat Influenza Viruses

By analyzing more than 500 monoclonal antibodies (mAbs) derived from B cells induced by numerous influenza virus vaccines and infections, we found mAbs targeting conserved neutralizing influenza virus hemagglutinin epitopes were polyreactive.

Regulatory T Cell-Derived TGF-β1 Controls Multiple Checkpoints Governing Allergy and Autoimmunity

The mechanisms by which regulatory T (Treg) cells differentially control allergic and autoimmune responses remain unclear. Researchers showed that Treg cells in food allergy had decreased expression of transforming growth factor beta 1 (TGF-β1) because of interleukin-4- and signal transducer and activator of transciription-6-dependent inhibition of Tgfb1 transcription.

Long Non-Coding RNA PVT1 Facilitates High Glucose-Induced Cardiomyocyte Death Through the miR-23a-3p/CASP10 Axis

Investigators observed that plasmacytoma variant translocation 1 (PVT1) and caspase‐10 were upregulated while miR‐23a‐3p was downregulated in high glucose‐induced cardiomyocytes. High glucose repressed cardiomyocyte activity and induced cardiomyocyte apoptosis, but this influence was antagonized by PVT1 knockdown or miR‐23a‐3p overexpression.
