pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

MicroRNA-196a increases apoptosis in B cells through downregulation of FOXO1
Molecules and Cells: MicroRNAs (miRNAs) are key regulators of cancer pathogenesis, and their expression is often dysregulated in cancer cells. The role of miR-196a-5p has been investigated in various types of cancers.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

B-cell and T-cell activation in South African HIV-1-positive non-Hodgkin’s lymphoma patients
Southern African Journal of HIV Medicine, 2018 Background: Altered immune mechanisms play a critical role in the pathogenesis of non-Hodgkin’s lymphoma (NHL). HIV-1 (HIV) infection is associated with a state of excessive T-cell activation, which can lead to increased T-cell turnover and lymph node ...

Role of p52 (NF-κB2) in LPS tolerance in a human B cell line [PDF]
, 1999 Cells of the weakly CD14 positive human B cell line RPMI 8226, clone 1, will mobilize NF-κB (p50/p65 and p50/p50) proteins and produce TNF mRNA when stimulated with lipopolysaccharide (LPS), When such cells are precultured with a low amount of LPS (50 ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
