"WebbLoss of miR-181a/b-1 resulted in inefficient de novo generation of Treg cells in the thymus but simultaneously permitted homeostatic expansion in the periphery in the absence of competition. Modulation of T-cell receptor (TCR) signal strength in vivo indicated that miR-181a/b-1 controlled Treg-cell formation via establishing adequate signaling thresholds. " - Thymic activity

WebbThymic peptides such as thymulin stimulate the release of GH, PRL, LH, and FSH. A thymosin component peptide, thymosin β4, appears particularly effective in stimulating the pituitary–gonadal axis by promoting Gn-RH release at the level of the hypothalamus and LH release from the pituitary. http://proboostmed.com/wordpress/wp-content/uploads/2012/06/white_blood_03.pdf
