Term:
MHC Class II RT1A-positive spinal cord ventral horn area to total spinal cord ventral horn area ratio
A calculated measurement in which the value representing the area of the spinal cord vental horn that demonstrates histological staining for the MHC Class II RT1A molecule is divided by value representing the total area of the spinal cord ventral horn, and presented as a ratio, fraction, quotient or percentage. MHC Class II RT1A is a class II major histocompatibility complex protein that is involved in antigen presentation and has been implicated in allograft rejection and autoimmunity.
