Sepsis is a life-threatening condition that affects the cardiovascular and renal systems. Severe hypotension during sepsis compromises tissue perfusion, which can lead to multiple organ dysfunction death. Phosphodiesterase 5 (PDE5) degrades intracellular cyclic guanosine monophosphate (cGMP) levels promotes vasodilatation in specific sites. Our previous studies show inhibiting cGMP production early increases mortality, implying protective role for production. Then, we hypothesized increased...

Inhibition of either P2Y12 receptor or the nucleotide-binding oligomerization domain- (NOD-) like pyrin domain containing 3 (NLRP3) inflammasome provides cardioprotective effects. Here, we investigate whether direct NLRP3 inhibition exerts additive effects on myocardial protection induced by antagonist Ticagrelor. Ticagrelor (150 mg/kg) was orally administered to rats for three consecutive days. Then, isolated hearts underwent an ischemia/reperfusion (30 min ischemia/60 reperfusion; IR)...

Obesity, one of the most frequent health problems in adult population, is a condition characterized by excessive white adipose tissue accumulation and accompanied increased risk to develop other disorders such as type II diabetes, cardiovascular disorders, physical disability, frailty sarcopenia. Total fat mass frequently increases during aging, often coexisting with sarcopenia, thus resulting an emerging defined sarcopenic obesity (SO). Our previous data demonstrated relevant role bromo...

KRIT1 loss-of-function mutations underlie the pathogenesis of Cerebral Cavernous Malformation (CCM), a major vascular disease affecting central nervous system (CNS). However, is also expressed outside CNS and modulates key regulators metabolic oxy-inflammatory pathways, including master transcription factor FoxO1, suggesting widespread functional significance. Herein, we show that KRIT1/FoxO1 axis implicated in liver functions antioxidative/antiglycative defenses. Indeed, by performing...

Septic shock, which is triggered by microbial products, mainly characterised inadequate tissue perfusion, can lead to multiple organ dysfunction and death. An intense release of vasoconstrictors agents occurs in the early stages ischemic injury. In this scenario, cGMP could play a key role counterbalancing these preventing damage.
