Prokaryotic defense systems: Diversity and evolutionary adaptation

mLife, Volume 5, Issue 1, Page 3-16, February 2026.
Abstract Bacteriophages and archaeal viruses are the most abundant biological entities on Earth. Through a long‐standing co‐evolutionary arms race, they have driven the emergence of a diverse repertoire of prokaryotic defense systems. This review summarizes these systems, highlighting their diverse antiviral mechanisms across distinct stages of viral ...

Ruling out pyridine dinucleotides as true TRPM2 channel activators reveals novel direct agonist ADP-ribose-2'-phosphate [PDF]

, 2015
Transient receptor potential melastatin 2 (TRPM2), a Ca(2+)-permeable cation channel implicated in postischemic neuronal cell death, leukocyte activation, and insulin secretion, is activated by intracellular ADP ribose (ADPR).

Cyclic ADP ribose is a novel regulator of intracellular Ca 2+ oscillations in human bone marrow mesenchymal stem cells [PDF]

, 2011
Bone marrow mesenchymal stem cells (MSCs) are a promising cell source for regenerative medicine. However, the cellular biology of these cells is not fully understood. The present study characterizes the cyclic ADP-ribose (cADPR)-mediated Ca 2+ signals in

Oxytocin Enhances Demethylation Through TET Enzyme Expression in Neurons of Aged Mice: Oxytocin as a Potential Antiaging Peptide

Aging Cell, Volume 24, Issue 10, October 2025.
DNA methylation, mitochondrial dysfunction, inflammation, and senescence interact to form a vicious cycle. Here we report that oxytocin interrupts this vicious cycle by increasing TET2 expression, inducing DNA demethylation in aged neurons and raising plasma oxytocin levels, decreasing systemic inflammation.

Design, synthesis and biological characterization of novel inhibitors of CD38 [PDF]

, 2011
Human CD38 is a novel multi-functional protein that acts not only as an antigen for B-lymphocyte activation, but also as an enzyme catalyzing the synthesis of a Ca 2+ messenger molecule, cyclic ADP-ribose, from NAD +.

Exploring NAD(+) metabolism in host-pathogen interactions [PDF]

, 2016
Nicotinamide adenine dinucleotide (NAD+) is a vital molecule found in all living cells. NAD+ intracellular levels are dictated by its synthesis, using the de novo and/or salvage pathway, and through its catabolic use as co-enzyme or co-substrate.

Immune Cell Proteins and Parkinson's Disease: A Mendelian Randomization Analysis of Causal Associations

Brain and Behavior, Volume 15, Issue 7, July 2025.
Mendelian randomization (MR) analysis was applied to elucidate the causal relationship between immune cell proteins and PD. Our study reveals a possible causal effect of immune cell proteins on the risk of PD and provides new ideas for the prevention and management of PD through immune cell proteins.
