[Some experimental evidences for immune functions of interstitial plasma-cells of the submaxillary glands (author's transl)].

Interstitial plasma-like cells, constantly present in the submaxillary glands, are they endocrine cells or true plasma-cells? They do not show any change in case of hypertrophy of the salivary glands which is observed under isoproterenol repeated administration. In contrary their number increase greatly during the immunologic stimulation by human albumin injections in the Hamster cheek pouches. So, it does appear that they would be true plasma cells involved in immunoglobulins synthesis.
