SWAP70 and Guillain-Barre syndrome: Interestingly, statistical analysis of SWAP-70 and CD44s protein levels showed that SWAP-70 protein expression in GB tissues was significantly and positively correlated with CD44s protein expression in GB tissues with a correlation coefficient of r = 0.683, suggesting that SWAP-70 and CD44s may have a regulatory relationship in the development and progression of GBs (Fig. 4a, b).
