A time-course of single nuclei RNA-seq of the mouse placenta identifies trophoblast subtypes and the genes, signaling events, and transcriptional networks important for their differentiation, maintenance, and function.

The sphingosine 1-phosphate receptor-1 (S1PR1) signals in heterogenous populations of mouse adventitial lymphatic (LEC) and arterial endothelial cells (aEC1, aEC2) to regulate chromatin and the transcriptome, thus affecting their phenotypes.
Impairment of the autocrine S1PR1-Gi signaling on HEVs results in high-endothelial cell apoptosis, reduced CCL21-secretion from HEVs, and cessation of HEV-DC interactions and lymphocyte immigration across the high-endothelial barrier.
RBM7 functions as a novel regulator of MFGE8 alternative splicing and p65 phosphorylation to counteract the metastatic potential of breast cancer, offering novel mechanistic insights into how abnormal splicing contributes to tumor aggressiveness.
Self-reactive CD4+ thymocytes have a broad impact on the composition of medullary thymic epithelial cell (mTEC) subsets by acting upstream of Aire+ mTECs, which conditions the induction of T-cell tolerance.

Defining the probability of bacterial disease among children with severe malaria allows the integration of bacteraemia and severe malaria genome-wide association study data, identifying a novel risk locus for invasive bacterial disease.

PASC (post-acute sequelae of SARS-CoV-2 infection) is an enduring and debilitating illness caused by a persistent virus that promotes inflammation, coagulation, and autoimmunity complications in millions of patients initially diagnosed with COVID-19, but with no known standardized treatment regimen.
