|Comment||Localization of thyrotropin receptor and thyroglobulin in the bovine corpus luteum. Mutinati M et al. The receptor of the Thyroid Stimulating Hormone (TSHr) and thyroglobin (TGB), are two proteic factors necessary for the synthesis of hormones, in the thyrocite. In mammals, many immuno-histochemical reports indicate the presence of the TSHr in extra-thyroidal tissues, but not in the ovary. Triiodothyronine (T(3)) and thyroxine (T(4)) have been widely shown to affect ovarian functions and the synthesis of progesterone (P(4)). The aim of this study was to determine if by immunohistochemistry techniques TSHr and TGB could be found in the bovine corpora haemorragica, lutea and albicantia. A primary rabbit polyclonal antibody against human TSHr and a primary rabbit polyclonal antibody against human TGB were employed. Furthermore, the accuracy of bovine thyroid to the antibodies used in this study was tested. A positivity reaction for the anti-TSHr serum in the large luteal cells and immunostaining of both small and large luteal cells with the anti-TGB serum occurred only in mature corpora lutea. No immunostaining was detected in stromal cells, blood and lymphatic vessels and in corpora haemorragica and albicantia. Bovine thyroid tissue showed immunostaining to both the antibodies employed. These data suggest that the luteal cells of mature corpora lutea may be involved in the synthesis of thyroid hormones, which may modulate P(4) synthesis, acting in an autocrine and paracrine way.|
