To translate, or not to translate: viral and host mRNA regulation by interferon-stimulated genes. [PDF]
, 2015 Type I interferon (IFN) is one of the first lines of cellular defense against viral pathogens. As a result of IFN signaling, a wide array of IFN-stimulated gene (ISG) products is upregulated to target different stages of the viral life cycle.

BMEMat, EarlyView.The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.

Cellular functions of the ClpP protease impacting bacterial virulence
Frontiers in Molecular Biosciences, 2022 Proteostasis mechanisms significantly contribute to the sculpting of the proteomes of all living organisms. ClpXP is a central AAA+ chaperone-protease complex present in both prokaryotes and eukaryotes that facilitates the unfolding and subsequent ...

Mechanistic insights into bacterial AAA+ proteases and protein-remodelling machines [PDF]
Nature Reviews Microbiology, 2015 To maintain protein homeostasis, AAA+ proteolytic machines degrade damaged and unneeded proteins in bacteria, archaea and eukaryotes. This process involves the ATP-dependent unfolding of a target protein and its subsequent translocation into a self-compartmentalized proteolytic chamber.

Developmental Dynamics, EarlyView.Abstract Background Schwann cells provide peripheral nerve trophic support, myelinate axons, and assist in repair. However, Schwann cell repair capacity is limited by chronic injury, disease, and aging. Schwann cell reprogramming is a cellular conversion strategy that could provide a renewable cell supply to repair injured nerves.

A Lon-like protease with no ATP-powered unfolding activity. [PDF]
PLoS ONE, 2012 Lon proteases are a family of ATP-dependent proteases involved in protein quality control, with a unique proteolytic domain and an AAA(+) (ATPases associated with various cellular activities) module accommodated within a single polypeptide chain.

Inflammation, Immunity, and Cardiovascular Diseases
Med Research, EarlyView.Cardiovascular stress signals (e.g., hemodynamic shear, oxidized lipids, and ischemia) act on endothelial and immune cells to activate and amplify inflammation through NF‐κB, the NLRP3 inflammasome, and JAK/STAT signaling, inducing proinflammatory cytokines/chemokines (IL‐6, IL‐1β, TNF‐α, and CCL2) and self‐amplifying circuits; clinically, inflammatory
