Exhaustion of CD4+ T cells is associated with bacterial load in active tuberculosis patients. (PubMed, Microb Pathog) - "In TB patients, mycobacterial burden was associated with alterations in T cell populations and functional exhaustion. Overall T cell counts were reduced, whereas CD4+ T cells were relatively elevated. Moreover, CD4+ T cell exhaustion positively correlated with mycobacterial load. These findings highlight the potential value of immunotherapeutic interventions in patients with high bacterial burdens and provide a theoretical rationale for incorporating host-directed strategies into future TB treatment regimens."

AID/HAT1-mediated epigenetic priming of JAG1/NOTCH signaling drives tumor microenvironment reprogramming in TNBC. (PubMed, Cell Signal) - "Pharmacological disruption using 4-Deoxyuricine (AID antagonist) and MG149 (HAT1 inhibitor) reduces JAG1 acetylation, attenuates NOTCH signaling, and reshapes the TME by depleting AID/HAT1-JAG1 axis and enhancing the infiltration of T cells, NK cells, and B cells...These results resolve the paradox of NOTCH inhibitor resistance by identifying JAG1's epigenetic priming as a prerequisite for ligand-receptor signaling. Targeting the AID/HAT1-JAG1 axis offers a dual therapeutic strategy to overcome TME-mediated therapy resistance and provides a blueprint for precision immunotherapy in AID-positive TNBC subgroups."

Challenges in the Development of NK-92 Cells as an Effective Universal Off-the-Shelf Cellular Therapeutic. (PubMed, J Immunol) - "Previous studies have demonstrated polymorphism at the 72nd amino acid of the NKG2D on human NK cells, with NKG2D72Thr exhibiting a superior activation effect on NK cells compared with NKG2D72Ala.
