Effects of cervical spinal cord injury (cSCI) in levels of autoreactive and total immunoglobulins in serum. (A) Quantification of autoreactive serum immunoglobulin G (IgG) and IgM against spinal cord lysate in rats with cSCI or sham injury at 2 weeks. There was no statistically significant difference between the groups. Mann-Whitney test, n = 7/group (IgG), Independent Student's t-test, n = 6-7/group (IgM), Bars indicate mean. (B) Quantification of total serum IgG and IgM immunoglobulins in SCI or sham rats at 2 weeks. IgG and IgM immunoglobulins declined significantly as a result of cSCI. Independent Student's t-test, *p < 0.05, n = 6-9/group, mean ± standard error of the mean. Color image is available online at www.liebertpub.com/neu
