Role of opioid signaling in kidney damage during the development of salt-induced hypertensionStimulation of kappa opioid receptors modulates calcium influx via TRPC6 channels in podocytes, which ultimately compromises the integrity of the glomerular filtration barrier and promotes a marked worsening of blood pressure control and renal damage.
Human G-MDSCs are neutrophils at distinct maturation stages promoting tumor growth in breast cancerThis study shows that immunosuppressive primary breast cancer patient–derived G-MDSCs (PMN-MDSCs) are neutrophils at a range of maturations stages, and provides in vivo evidence for that human G-MDSCs also promote tumor growth and myeloid immune cell exclusion.
Multiplexed chemogenetics in astrocytes and motoneurons restore blood–spinal cord barrier in ALSChemogenetic motoneuron excitation and astrocyte GPCR-Gi signaling restore blood–spinal cord barrier, disrupted in four ALS mouse models, revealing its role in disease progression but not initiation.
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.
