High magnification revealed binding of IgG from the patient's CSF to membranes of PC dendrites and axons. Panel A shows transverse sections and panel B depicts longitudinal sections of distal PC dendrites (mouse tissue). Panel C shows three longitudinal sections of proximal PC dendrites (monkey tissue). Panel D consists of a composite of transverse and longitudinal sections of monkey PC axons. A goat anti-human IgG antibody labeled with AF488 was used to visualize bound IgG.
