Histone deacetylase 7 mediates lipopolysaccharide-inducible mitochondrial fission in macrophages.

Histone deacetylase 7 (HDAC7) drives several immunometabolism-related processes in macrophages including lipopolysaccharide (LPS)-inducible glycolysis and inflammatory mediator production. Using an advanced biotin ligase TurboID system in human macrophages, we report 104 candidate HDAC7 interaction partners that may contribute to its immunometabolic functions. One such protein is the mitochondrial fission-promoting GTPase dynamin-related protein 1 (DRP1), which associates with HDAC7 in cells.

Enhancing the Intrinsic Antiplasmodial Activity and Improving the Stability and Selectivity of a Tunable Peptide Scaffold Derived from Human Platelet Factor 4.

The control of malaria, a disease caused by parasites that kills over half a million people every year, is threatened by the continual emergence and spread of drug resistance. Therefore, new molecules with different mechanisms of action are needed in the antimalarial drug development pipeline. Peptides developed from host defense molecules are gaining traction as anti-infectives due to theood of inducing drug resistance.

Mitochondrial dynamics in macrophages: divide to conquer or unite to survive?

Mitochondria have long been appreciated as the metabolic hub of cells. Emerging evidence also posits these organelles as hubs for innate immune signalling and activation, particularly in macrophages. Macrophages are front-line cellular defenders against endogenous and exogenous threats in mammals.
