MITOCHONDRIA-CONTROLLED SIGNALING MECHANISMS OF BRAIN PROTECTION IN HYPOXIA

open access: yesFrontiers in Neuroscience, 2015
The article is focused on the role of the cell bioenergetic apparatus, mitochondria, involved in development of immediate and delayed molecular mechanisms for adaptation to hypoxic stress in brain cortex.

XIAP Deficiency Impairs Colonic Tuft Cell Development and Predisposes to Crohn's Disease

open access: yesMedComm, Volume 7, Issue 5, May 2026.
XIAP deficiency leads to impaired colonic tuft cells development and JAK–‐STAT pathway hyperactivation in CD patients and mice. Mechanically, XIAP regulates tuft cells development through Wnt–‐TLE4/TCF–‐ASCL2 signaling. Tuft cells deficiency predisposes XIAP‑‐deficient CD patients or Xiap−/−‐/‐ mice to hazardous microbial effects, driving colonic ...

Targeting Tumor Stroma: Current Challenges and Future Directions

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Figure 1. Mechanism of ECM reprogramming. Cancer‐associated fibroblasts (CAFs), cancer‐associated macrophages (CAMs), and other mesenchymal cells alter the ECM composition and increase its stiffness by depositing matrix components such as collagen and hyaluronic acid, and secreting cross‐linking agents like lysyl oxidase homolog 2 (LOXL2).

Aging‐Driven Immunosuppression: The Role of Tregs in the Ovarian Tumor Microenvironment

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
In the aged ovarian TME, cancer cells exhibit increased succinate production. Elevated extracellular succinate activates the SUCNR1 receptor on Tregs, promoting their recruitment and contributing to an immunosuppressive environment. This leads to diminished anti‐tumor T cell responses and reduced survival.

Succinate activates fibroblasts through GPR91-HIF-1α-TGF-β1-Smad signaling

open access: yesJournal of Radiation Research and Applied Sciences
Objective: To explore the role of succinate in age-related cardiac fibrosis and its mechanisms. Methods: In this study, we established three experimental models: naturally aged mice, young mice administered succinate by drinking water, and cultured NIH ...

The succinate receptor as a novel therapeutic target for oxidative and metabolic stress-related conditions.

open access: yesFrontiers in Endocrinology, 2012
The succinate receptor (also known as GPR91) is a G protein-coupled receptor that is closely related to the family of P2Y purinoreceptors. It is expressed in a variety of tissues, including blood cells, adipose tissue, the liver, retina and kidney.

Dietary anthocyanidin pelargonidin activates G protein‐coupled receptor 35

open access: yesThe FEBS Journal, Volume 293, Issue 5, Page 1386-1399, March 2026.
Pelargonidin, a red‐fruit‐derived anthocyanidin, was newly identified as a dietary agonist of GPR35, a metabolite‐sensing GPCR implicated in anti‐inflammation. Through screening of dietary compounds, pelargonidin emerged as a potent GPR35 agonist, attenuating inflammation in human intestinal cells.

GPR91 deletion enhances mast cell activation while preventing arthritic disease

open access: yes, 2016
While searching for a role of succinate on skin inflammation we discovered that its specific receptor, GPR91/SUCNR1 is also expressed by mast cells. Sucnr1-/- mast cells displayed enhanced reactivity to allergen-IgE crosslinking.

Rôle du GPR91 dans la réponse à l'hypoxie-ischémie et l'importance de sa localisation intracellulaire [PDF]

open access: yes, 2013
L'adaptation à l'environnement est essentielle à la survie cellulaire et des organismes en général. La capacité d'adaptation aux variations en oxygène repose sur des mécanismes de détection de l'hypoxie et une capacité à répondre en amorçant un programme

Gut microbiota and central nervous system's direct bidirectional regulation: The mechanisms of the gut–brain axis in irritable bowel syndrome

open access: yesClinical and Translational Discovery, Volume 6, Issue 1, February 2026.
Gut microbiota directly modulates central nervous system activity via vagal, sympathetic and sensory neural circuits. Brainstem nuclei integrate microbial signals to regulate gut motility, secretion and visceral sensitivity. DRG neurons and stress‐responsive pathways link microbial cues to host defence and epithelial homeostasis. Dysregulated gut–brain
