[Role of NLRP3 inflammasome in heart failure and traditional Chinese medicine intervention: a review].

Heart failure is characterized by high incidence and mortality rates, and the search for effective treatment strategies for heart failure and the improvement of clinical outcomes have always been important research directions. Imbalanced inflammation has been proven to be one of the critical pathological factors in heart failure, positively correlated with adverse events such as impaired cardiac function and myocardial fibrosis. In recent years, studies have confirmed that the activation of the NOD-like receptor thermal protein domain-associated protein 3(NLRP3) inflammasome plays a common regulatory role in the inflammation imbalance induced by various factors in heart failure.

Targeting the neurovascular unit in brain trauma.

Although the neurovascular unit was originally developed as a conceptual framework for stroke, it is now recognized that these cell-cell interactions play critical roles in many other CNS disorders as well. In brain trauma, perturbations within the neurovascular unit may be especially important. Changes in neurovascular coupling may disrupt blood flow and metabolic regulation.

Role of SIRT1 in Streptococcus pneumoniae-induced human β-defensin-2 and interleukin-8 expression in A549 cell.
