LRRK2 couples brain-derived neurotrophic factor (BDNF) signaling to synaptic actin remodeling, defining a novel mechanism of LRRK2 synaptic function and highlighting early, targetable pathways in Parkinson’s disease.
Cell-surface heparan sulfate clusters, not the generally assumed ACE2, mediate SARS-CoV-2 attachment and endocytic entry, fundamentally revising the viral entry paradigm and establishing heparan sulfate as a primary therapeutic target.
