The origin of immunoglobulins in salivary secretion of sheep.
A comparative study was made on the secretion of IgG1 and IgA into parotid and submaxillary saliva of sheep. The purpose of the study was to examine the suggestion that in the external secretory organs of ruminants there is an inverse relationship between the capacity to selectively transfer IgG1 and the development of the IgA secretory system. Despite a marked difference in the secretion of IgA between the parotid and submaxillary salivary glands, the magnitude of selective transfer of IgG1 was similar. Thus, there appears to be no relationship between the selective transfer of IgG1 and the secretion of IgA into the saliva of sheep.
