Mitochondrial spongiotic brain disease: astrocytic stress and harmful rapamycin and ketosis effectAstrocyte-specific mtDNA depletion causes spongiotic encephalopathy, aggravated by ketogenic diet or rapamycin. Astrocytes, but not neurons, drive mitochondrial integrated stress response in the CNS.
BH4 activates CaMKK2 and rescues the cardiomyopathic phenotype in rodent models of diabetesThis study reports that BH4 activates CaMKK2/PGC-1α; signaling pathway and has a therapeutic effect on diabetic cardiomyopathy.
Loss of polycystins suppresses deciliation via the activation of the centrosomal integrity pathwayDeletion of the polycystins activates components of the centrosomal integrity pathway, resulting in delayed cell deciliation and prolonged activation of cilia-related signaling pathways.
Paneth cell α-defensin misfolding correlates with dysbiosis and ileitis in Crohn’s disease model miceThis study provides novel insight into Crohn’s disease where α-defensin misfolding resulting from excessive ER stress in Paneth cells induces dysbiosis and disease progression.
Dynamic changes in the regulatory T-cell heterogeneity and function by murine IL-2 muteinSingle-cell RNA-seq analysis reveals that IL-2 mutein treatment expands multiple sub-states of regulatory T cells with superior suppressive function in mice.
Keratinocyte interleukin-36 receptor expression orchestrates psoriasiform inflammation in miceIL-36 stimulation of keratinocytes orchestrates key pathogenic inflammatory responses in psoriatic skin.
TRAP1 chaperone protein mutations and autoinflammationThis study identifies patients with autoinflammation and mutations affecting the mitochondrial/ER protein chaperone TRAP1, either alone or digenic, with MEFV mutation possibly synergizing to produce severe disease. TRAP1 mutations lead to increased mitochondrial reactive oxygen species and may contribute to autoinflammation.
aYAP modRNA reduces cardiac inflammation and hypertrophy in a murine ischemia-reperfusion modelTransient activation of YAP with a modified mRNA after ischemia-reperfusion stress reduces cardiac inflammation, attenuates cardiac hypertrophic remodeling and helps to salvage the myocardium.
Expression of AXL receptor tyrosine kinase relates to monocyte dysfunction and severity of cirrhosisImmune dysfunction determines morbidity and mortality in liver cirrhosis. Distinct AXL-expressing circulating monocytes, which regulate antimicrobial responses, expand with progression of the disease.
Thymosin β4 promotes autophagy and repair via HIF-1α stabilization in chronic granulomatous diseaseThis study demonstrates that thymosin β4 stabilizes HIF-1a to promote autophagy and up-regulate genes involved in tissue and mucosal barrier protection in chronic granulomatous disease.
