Background: SARS-CoV-2 infection is marked by an excessive inflammatory response, leading to elevated production of pro-inflammatory cytokines through activation of intracellular pathways like mitogen-activated protein kinase (MAPK). Viruses can use the MAPK signaling pathway to their advantage, but the relationship of this pathway to the severe SARS-CoV-2 period has not been fully elucidated. MAP2K4 is involved in the MAPK signaling pathway and affects cellular processes such as cell-cell junction, cell proliferation, differentiation and apoptosis.

Axon pathfinding is a highly dynamic process regulated by the interactions between cell-surface guidance receptors and guidance cues present in the extracellular environment. During development, precise axon pathfinding is crucial for the formation of functional neural circuits. The spatiotemporal expression of axon guidance receptors helps the navigating axon make correct decisions in a complex environment comprising both attractive and repulsive guidance cues.

Background: Anti-Activin Receptor Type IIA and Type IIB antibody (αActRIIA/IIB ab) is a recently developed drug class that targets the activin receptor signalling pathway. Inhibition of receptor ligands (activins, myostatin, growth differentiation factor 11, etc.) can lead to skeletal muscle hypertrophy, bone formation, and increased haematopoiesis.

One of the promising sources for creating specialized foods is the biomass of Arthrospira platensis food microalgae. Biomass of A. platensis and its aqueous extracts are used as a source of bioactive compounds, primarily phycocyanins which are protein macromolecules that largely determine the antioxidant, immunomodulatory and anti-inflammatory properties of this cyanobacterium.

() exhibits aberrant changes in patients with colitis, and it has been reported to dominate the colonic mucosal immune response. Here, we found that PMA1 expression was significantly increased in from patients with IBD compared to that in healthy controls. A Crispr-Cas9-based fungal strain editing system was then used to knock out PMA1 expression in .
