Problems may develop when ROS production remains excessive or antioxidant defenses are insufficient
Notably, H2R signaling enhances antigen uptake and cross-presentation (29), decreases the IFN- and TNF- produced by pDCs (30), and promotes Th2-skewing DC polarization (31, 32)
Newly differentiated OLs extend their processes and quickly rearrange their membranes to generate internodes around multiple axons through a series of coordinated steps that include: (1) identification and signaling with the target axons, (2) axonal wrapping with membrane outgrowth, (3) transporting membrane components, (4) compacting myelin sheaths, and (5) node establishment (Simons et al., 2024)
