Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

PDE4 Inhibition in Dermatologic Disease: Impacts Beyond Inflammation
This graphical abstract demonstrates the comprehensive mechanism of PDE4 inhibition in skin physiology. By increasing intracellular cAMP and activating PKA, PDE4 inhibitors exert pleiotropic effects, including immune modulation, pigmentation regulation, barrier enhancement, sensory neuron modulation, and improved wound healing with reduced fibrosis ...

Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Treatment‐associated phenotype switching between psoriasis and atopic dermatitis
This international, multicentre real‐world study of 148 patients’ documents treatment‐associated, bidirectional phenotype switching between psoriasis and atopic dermatitis. Psoriasis‐to‐eczematous switches occurred predominantly with IL‐17 and IL‐23 inhibitors, whereas AD‐to‐psoriasiform switches occurred exclusively during treatment with biologic ...

Pathophysiology and emerging treatments for dermographic, cholinergic and cold urticaria
This review illustrates key proposed mast cell‐mediated activation pathways in dermographic, cholinergic and cold urticaria, highlighting IgE‐dependent and ‐independent mechanisms. These pathways are increasingly targeted by emerging drugs, aiming to interrupt mast cell activation and mediator release, offering more precise, mechanism‐based treatment ...

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility
Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...
