Popis: Cerebrospinal fluid (CSF) and serum antibody responses to albumin administered into CSF or muscle have been compared with respect to titer, isotype profile and complement-fixing activity in a rat model with normal brain barrier function. CSF/serum titer ratios and the ratio of IgG subclasses, IgG1/IgG2, were both elevated following CSF immunization. In contrast, there was no difference in complement-fixing activity between antibodies elicited by the two routes of immunization. It is suggested that intrathecal antibody synthesis accounts for the elevated CSF antibody titers in CSF-immunized rats, providing the first example of central nervous system antibody synthesis in an animal with normal brain barrier permeability.
