The ubiquitously expressed, multifunctional scaffolding proteins β-arrestin1 and β-arrestin2 each affect inflammatory signaling in a variety of cell lines. In addition to binding the carboxyl-terminal tails of innumerable 7-transmembrane receptors, β-arrestins scaffold untold numbers of other plasma membrane and cytoplasmic proteins. Consequently, the effects of β-arrestins on inflammatory signaling are diverse, and context-specific. This review highlights the roles of β-arrestins in regulating canonical activation of the pro-inflammatory transcription factor NFκB.

Contemporary osteoporosis treatment often neglects the intricate interactions among immune cells, signaling proteins, and cytokines within the osteoporotic microenvironment. Here, we developed core-shell nanocapsules composed of a cationized lactoferrin core and an alendronate polymer shell. By tuning the size of these nanocapsules and leveraging the alendronate shell, we enabled precise delivery of small interfering RNA targeting the Semaphorin 4D gene (siSema4D) to specific bone sites.

Objectives: COVID-19 and systemic sclerosis (SSc) share multiple similarities in their clinical manifestations, alterations in immune response, and therapeutic options. These resemblances have also been identified in other immune-mediated inflammatory diseases where a common genetic component has been found. Thus, we decided to evaluate for the first time this shared genetic architecture with SSc.

Background: Acute systemic inflammation affects many organs and it occurs in a wide range of conditions such as acute lung injury (ALI). Inflammation-triggered oxidative pathways together with the caspase activation seen in ALI, result in apoptosis. Dapagliflozin (DPG) is an agent that is known to have oxidative stress-reducing and anti-inflammatory effects in many tissues.
