The origin and specificity of intrathecal IgG in chronic relapsing experimental allergic encephalomyelitis

Abstract

The source of IgG in the cerebrospinal fluid (CSF) in guinea pigs with chronic relapsing experimental allergic encephalomyelitis (CR-EAE) was investigated using quotient analysis of total IgG and albumin concentrations and by computing CSF-plasma ratios of specific IgG concentrations. Increased blood-CSF barrier (B-CSFB) permeability was shown by elevated albumin quotients in both relapse and remission phases of CR-EAE and intrathecal production of IgG was indicated by raised ratios of IgG to albumin in the CSF. Intrathecal IgG synthesis was greatest in guinea pigs which had little B-CSFB damage. When enzyme-linked immunosorbent assays (ELISA) for whole cord, myelin basic protein (MBP) or Mycobacterium tuberculosis were performed with CSF and plasma adjusted to the concentration of total IgG, the CSF/plasma ratios of ELISA results for specific antibodies were less then unity and ratios for whole cord and MBP were lower than those for M. tuberculosis. There was thus no evidence for a selective increase in the CSF of antibody specific either for the neuroantigens tested or for adjuvant components. The CSF-plasma ratios for each specific antibody were inversely correlated with the extent of total IgG intrathecal synthesis, suggest...Continue Reading

CSF & Lymphatic System

This feed focuses on Cerebral Spinal Fluid (CSF) and the lymphatic system. Discover the latest papers using imaging techniques to track CSF outflow into the lymphatic system in animal models.

B cell Activation

B cell activation is initiated by the ligation of the B cell receptor with antigen and ultimately results in the production of protective antibodies against potentially pathogenic invaders. Here is the latest research.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
