Neurotransmitters are increasingly recognized to play important roles in limiting anti-tumor immunity. N-acetyl-aspartyl-glutamate (NAAG) has been extensively studied in neurological disorders; however, its potential role in restricting anti-tumor immunity has not been investigated. Here, we demonstrated that NAAG or its synthetase RimK-like family member B (RIMKLB) significantly disrupted anti-tumor immunity by rewiring the myeloid progenitor differentiation of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs), which in turn promoted breast cancer growth and metastasis.

Endometriosis is an estrogen-dependent benign disease characterized by growth of the endometrial tissue outside the uterine wall. Several reports suggest the possibility of the pathogenesis and recurrence of endometriosis being related to functions of stem/progenitor cells of the endometrium. The drawback of the widely used method of using Hoechst 33342, a fluorescent dye, to collect stem cell-like populations, is the requirement of an ultraviolet (UV) excitation source not commonly provided on standard flow cytometers.

- FT596 is a novel cancer therapy using iPSC-derived CAR NK cells targeting CD19, designed to assess its safe dosage and effectiveness alone and with rituximab in patients with B-cell lymphoma.
- This phase 1 trial involved patients with relapsed or refractory B-cell lymphoma, administering FT596 after chemotherapy, with separate regimens for those receiving rituximab and those who did not.
- The study measured potential side effects while determining the optimal dose of FT596 and allowed modifications to the treatment based on patient tolerance and response.
Population size, income and poor sanitation interact to explain widespread streamwater contamination by antidepressants in the Metropolitan Region of São Paulo.

The expansion of urban settlements over native environments may expose biodiversity to a host of emerging contaminants, with unintended ecological effects. This study evaluated patterns of contamination of streamwater by antidepressants in the Upper Tietê River Basin, a watershed of high social, economic and environmental relevance for comprising both the largest urban settlement in South America (the Metropolitan Region of São Paulo) and remnants of a globally important biodiversity hotspot (the Atlantic Rainforest). We sampled 53 third-order streams draining catchments regularly distributed across a gradient in urban cover.

Purpose Of Review: While lipid-lowering therapies demonstrate efficacy, many patients still contend with significant residual risk of atherosclerotic cardiovascular diseases (ASCVD). The intestine plays a pivotal role in regulating circulating lipoproteins levels, thereby exerting influence on ASCVD pathogenesis. This review underscores recent genetic findings from the last six years that delineate new biological pathways and actors in the intestine which regulate lipid-related ASCVD risk.
