C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Daratumumab Treatment for Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP): A Case Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune‐mediated neuropathy featuring progressive weakness, sensory deficits, and areflexia. While corticosteroids, intravenous immunoglobulin, and plasmapheresis are effective first‐line immunotherapies, a subset of patients remains treatment‐refractory.
