The thymus-neuroendocrine axis: physiology, molecular biology, and therapeutic potential of the thymic peptide thymulin.
Thymulin is a thymic hormone exclusively produced by the thymic epithelial cells. It consists of a nonapeptide component coupled to the ion zinc, which confers biological activity to the molecule. After its discovery in the early 1970s, thymulin was characterized as a thymic hormone involved in several aspects of intrathymic and extrathymic T cell differentiation. Subsequently, it was demonstra...
متن کاملPhysiology and therapeutic potential of the thymic peptide thymulin.
Thymulin is a thymic hormone exclusively produced by the epithelial cells of the thymus. After its discovery and initial characterization in the '70s, it was demonstrated that the production and secretion of thymulin are strongly influenced by the neuro-endocrine system. Conversely, a growing body of evidence, to be reviewed here, suggests that thymulin is a hypophysiotropic peptide. Additional...
متن کاملThe role of microRNAs and phytohormones in plant immune system
The plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. During the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ROS signaling, hormone activation and gene expression reprogramming. In plants, microRNAs (miRNAs) are key post-transcript...
متن کاملIdentification and functional activity of prolactin receptors in thymic epithelial cells.
Thymic epithelial cells (TECs), the major component of the thymic microenvironment, can be modulated by pituitary hormones. We have shown previously that prolactin (PRL) can influence the endocrine activity of TECs and stimulate TEC proliferation as well as cytokeratin expression, suggesting the existence of PRL receptors on TECs. Using a series of monoclonal antibodies (mAbs) to the extracellu...
متن کاملPlasma zinc level and thymic hormone activity in young cancer patients.
It has been reported that in many neoplastic diseases, including leukemia, alterations in plasma zinc levels may frequently occur, although the causes for such alterations have yet to be clearly defined. Since zinc is required to induce biological activity to thymulin (Zn-FTS), a biochemical defined thymic hormone, and marginal zinc deficiencies may prevent its peripheral biological activation,...
