“…By far the most simple explanation would be a selectively increased permeability of the blood-cerebrospinal fluid barrier operating in favour of y globulin as compared with the albumin present in normal concentration, and since these proteins are widely separated in electric charge such a mechanism is readily conceivable. Frick and Scheid-Seydel (1958), studying this problem using radio-iodinelabelled globulin, suggest that the increase arises within the subarachnoid space on the basis of the distribution of labelled and unlabelled globulin molecules in the serum and cerebrospinal fluid of patients with multiple sclerosis. On the other hand, studies of the concentrations of antibodies following immunization show a remarkably constant ratio of cerebrospinal fluid to blood titres, and, as this ratio is altered in multiple sclerosis (Clark, 1963) Kuwert, Fimhaber, and Pette (1964) but this negative finding is unlikely to explain the increase in y globulin.…”

“…As alterações no teor da globulina gama, além de sugerirem a participação das proteínas desse grupo no transporte de anticorpos específicos, permitem relacionar essa globulina à atividade dos elementos do sistema retículo-endotelial (SRE) sediados no SNC e em seus envoltórios, encarregados da reação imunopatológica de defesa. Um dos argumentos mais ponderáveis para justificar a assertiva de que essa globulina é gerada pelo SRE resultou de estudos sobre a passagem da globulina gama do soro para o LCR utilizando iôdo-radiativo 9 . Tais estudos demonstraram que essa fração passa do soro para o LCR de modo mais lento que a albúmina e que, em condições normais, todo o contingente presente no LCR é representado pela porção proveniente do sangue; entretanto em processos inflamatorios crônicos do SNC e das leptomeninges essa fração resulta, em sua maior parte, da elaboração local.…”

“…The proteins present in the CSF are derived primarily from serum (5)(6)(7)(8). The passage of these proteins across the blood-CSF barrier is inversely related to size, resulting in relatively greater amounts of small proteins than large proteins in the CSF compared with amounts present in the serum (9).…”
