Resveratrol is indicated to be involved in neuroprotection and anti-inflammation in epileptic rats. The molecular mechanism is still not fully understood. In this study, we investigated the role of resveratrol in nuclear factor-kappa B associated inflammatory responses induced by status epilepticus. Our data showed that seizures activated mammalian target of rapamycin (mTOR), increased the activity of nuclear factor-kappa B and promoted the expressions of inflammatory molecules including inducible nitric oxide synthase, cyclooxygenase-2 and interleukin-1β. Futhermore, resveratrol significantly inhibited the activation of nuclear factor-kappa B and the production of proinflammatory molecules via mTOR pathway. Additionally, we also proved that the inhibition of mTOR signal by resveratrol was mostly attributed to AMP-activated kinase (AMPK) activation. Altogether, our results suggest that resveratrol suppresses inflammatory responses induced by seizures partially via AMPK/mTOR pathway.

Targeted FTO knockout in endothelial cells Boosts adhesion and lowers inflammatory infiltration to alleviate pulmonary arterial hypertension.

Pulmonary arterial hypertension (PAH) is a syndrome characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, ultimately leading to right heart failure and even death. Increasing evidence implicates the fat mass and obesity-associated protein (FTO) in various metabolic and inflammatory pathways; however, its role in pulmonary endothelial function and PAH remains largely unexplored. In this study, we examined the effects of endothelial cell-specific FTO knockout on PAH development.

We evaluated enterocyte damage (IFABP), microbial translocation (sCD14), and inflammatory responses (TNF-α, IL-6, CRP) in 16 older adults (66-78 years) during 8 hours rest in conditions simulating homes maintained at 22°C (control), the 26°C indoor temperature upper limit proposed by health agencies, and homes without air-conditioning during heatwaves (31°C, 36°C). Relative to 22°C, IFABP was elevated ~181 pg/mL after exposure to 31°C (P=0.07), and by ~378 pg/mL (P<0.

In thrombosis and hemostasis, the formation of a platelet-fibrin thrombus or clot is a highly controlled process that varies, depending on the pathological context. Major signaling pathways in platelets are well established. However, studies with genetically modified mice have identified the contribution of hundreds of additional platelet-expressed proteins in arterial thrombus formation and bleeding.

The NLRP3 inflammasome is a fundamental component of the innate immune system, yet its excessive activation is intricately associated with viral pathogenesis. Porcine reproductive and respiratory syndrome virus type 2 (PRRSV-2), belonging to the family Arteriviridae, triggers dysregulated cytokine release and interstitial pneumonia, which can quickly escalate to acute respiratory distress and death. However, a mechanistic understanding of PRRSV-2 progression remains unclear.
