Thy-1 monoclonal antibodies (MAbs) have previously been shown to promote neurite outgrowth from retinal ganglion cells and a variety of other neurons. We have studied the effect on neurite outgrowth of several Thy-1 MAbs with quantitatively similar binding properties and found that only certain Thy-1 MAbs promote neurite outgrowth. This finding suggests that the antibody effects depend on specific interactions with one or more active sites on the Thy-1 glycoprotein.
