A3AR antagonism mitigates metabolic dysfunction-associated steatotic liver disease by exploiting monocyte-derived Kupffer cell necroptosis and inflammation resolution.

Background & Aims: Metabolic dysfunction-associated steatotic liver (MASLD) progression is driven by chronic inflammation and fibrosis, largely influenced by Kupffer cell (KC) dynamics, particularly replenishment of pro-inflammatory monocyte-derived KCs (MoKCs) due to increased death of embryo-derived KCs. Adenosine A3 receptor (A3AR) plays a key role in regulating metabolism and immune responses, making it a promising therapeutic target. This study aimed to investigate the impact of selective A3AR antagonism for regulation of replenished MoKCs, thereby improving MASLD.

Distinct network patterns emerge from Cartesian and XOR epistasis models: a comparative network science analysis.

Background: Epistasis, the phenomenon where the effect of one gene (or variant) is masked or modified by one or more other genes, significantly contributes to the phenotypic variance of complex traits. Traditionally, epistasis has been modeled using the Cartesian epistatic model, a multiplicative approach based on standard statistical regression. However, a recent study investigating epistasis in obesity-related traits has identified potential limitations of the Cartesian epistatic model, revealing that it likely only detects a fraction of the genetic interactions occurring in natural systems.
