Development of Peptide Glucosyltransferase Inhibitors With Comprehensive Coverage Across Clostridioides difficile Toxin B Sub‐Types

Biotechnology and Bioengineering, Volume 123, Issue 2, Page 310-323, February 2026.
ABSTRACT Clostridioides difficile infection presents an escalating clinical challenge due to the proliferation of hypervirulent and antibiotic‐resistant strains. The primary symptoms of disease, namely colitis and diarrhea, are induced by the release of two toxins: TcdA and TcdB.

Circulating RAC1 contributed to steroid-sensitive nephrotic syndrome: Mendelian randomization, single-cell RNA-sequencing, proteomic, and experimental evidence

Renal Failure
Objectives The small GTPase Rac1 (RAC1) has been linked to podocyte disorders and steroid-sensitive nephrotic syndrome (SSNS). The aim of this study was to explore and validate the potential causal association between circulating RAC1 and SSNS.Methods ...

Isoprenoids determine Th1/Th2 fate in pathogenic T cells, providing a mechanism of modulation of autoimmunity by atorvastatin. [PDF]

, 2006
3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase is a critical enzyme in the mevalonate pathway that regulates the biosynthesis of cholesterol as well as isoprenoids that mediate the membrane association of certain GTPases.

Hypercapnia Effects on Lung Function

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
CO2 is a signaling molecule that disrupts alveolar fluid clearance and ion transport, impairs alveolar repair, and promotes mitochondrial and endoplasmic reticulum dysfunction. It suppresses innate immunity, host defense, and inflammation, while increasing airway contractility.

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.

Tumor‐Associated Macrophages as Therapeutic Targets: Deciphering Interaction Networks and Advancing Clinical Translation

MedComm, Volume 7, Issue 2, February 2026.
Tumor‐associated macrophages are the most abundant immune cells in the tumor microenvironment, driving malignant progression and treatment resistance. This review summarizes the protumor mechanisms of TAMs (including phagocytosis modulation, metabolic reprogramming, exosomal communication, and immune interactions), evaluates three major strategies ...

Astrocyte Senescence Impairs Synaptogenesis due to Thrombospondin‐1 Loss

Aging Cell, Volume 25, Issue 2, February 2026.
Senescent hippocampal astrocytes lose TSP secretion, impairing excitatory synaptogenesis via the α2δ‐1 pathway. Restoring TSP‐1 rescues synaptic formation, revealing the contribution of astrocyte senescence to age‐related hippocampal synaptic decline.
