| pubmed-article:6771081 | pubmed:abstractText | The immunoperoxidase method has been used to demonstrate the presence of immunoglobulin-containing cells in the central nervous system in acute and convalescent phases of poliomyelitis. These cells were found in considerable numbers in the areas of damage during the acute phase, and persisted at the same sites, though in smaller numbers, during the convalescent phase for at least 8 months. Most of the positively stained cells were plasma cells. IgA was the commonest heavy chain type demonstrated, with lesser amounts also of IgG and, during the acute phase, IgM. In the acute phase more lambda than kappa light chain was demonstrated but in the convalescent phase this ratio was reversed. More light chain than heavy chain was demonstrable during the acute phase. The significance of these results is briefly discussed. | lld:pubmed |
