AB  - The study was designed to explore the expression of different neuropeptides, viz. vasoactive intestinal peptide (VIP), calcitonin gene related peptide (CGRP), substance P (SP), bombesin and motilin in the cells of fetal and adult human thymus. Immunohistochemical staining revealed that cortical and medullary thymocytes were labeled by all antibodies, except those specific for motilin. Immunoreactive VIP and SP were observed in the solitary epithelial cells located in the subcapsular/subtrabecular cortex, at the corticomedullary junction and in the medulla. The cells within the subcapsular/subtrabecular monolayer, rare solitary cells in the deep cortex and epithelial cell network in the medulla, were labeled with antibodies to CGRP and bombesin. Hassall's corpuscles were labeled with all antibodies except that specific for SP. The obtained data obtained testify to the expression of different neuropeptides in human thymic lymphoid and non-lymphoid cells and suggest a role for neuroendocrine hormone-mediated mechanisms in the regulation of thymic homeostasis in humans.

AB  - Bearing in mind the role of somatostatin in thymus functions, and changes of somatostatin level and expression of its receptors during postnatal life, the aim of this study was to investigate whether centrally applied SRIH-14 induces different changes in the thymic compartments and thymocyte profile in peripubertal and young adult rats. To this end, 4- and 10-week-old male AO rats were cannulated and treated intracerebroventriculary with three doses of SRIH-14, applied every other day. In peripubertal rats, SRIH-14 decreases thymic relative weight and volume, as well as the volume of thymic compartments, especially of deep cortex, as a result of thymocytes loss by apoptosis. Also, SRIH-14 increases the percentage of immature thymocytes preceding the DPTCRαβlow cells (DNTCRαβ-/low, DPTCRαβ-, SPCD8TCRαβ-/low and SPCD4TCRαβ-/low), decreases the percentages of DPTCRαβlow and DPTCRαβhi cells, while the relative proportion of CD4+/CD8+TCRαβhi cells remained unaltered. In young adult rats, SRIH-14 does not lead to changes in relative thymus weight, although decreases the thymic cortex cellularity and volume. In addition, decreases the percentage of DPTCRαβ-/hi cells and increases the percentages of cells within DNTCRαβhi and both SP subpopulations, but much more of the CD8+TCRαβhi subset. These results suggest that the effects of SRIH-14 on the thymus and thymocytes subpopulations are age-dependent.
AB  - Sa obzirom da literaturni podaci ukazuju da somatostatin ima uticaja na funkciju timusa, kao i da se tokom postnatalnog života menja nivo somatostatina i ekspresija njegovih receptora u timusu, cilj ovog rada je bio da se ispita da li SRIH- 14 davan intracerebroventrikularno u prepubertalnih i mladih odraslih pacova, dovodi do različitih promena u zonama timusa i profilu timocitnih subsetova. Mužjacima pacova AO soja, starim 4 i 10 nedelja, ugrađene su kanile u treću moždanu komoru i oni su tretirani somatostatinom, ukupno tri doze, ubrizgane svakog drugog dana. U prepubertalnih pacova tretman somatostatinom dovodi do smanjenja relativne mase i zapremine timusa, kao i zapremine timusnih zona, naročito dubokog korteksa, što je bila posledica gubitka timocita apoptozom. Takođe, SRIH-14 je doveo do povećanja procenta timocita nezrelog fenotipa (DNTCRαβ-/low, DPTCRαβ-, SPCD8TCRαβ-/low i SPCD4TCRαβ-/low) prekusora DPTCRαβlow subpopulacije, smanjenja procenta DPTCRαβlow i DPTCRαβhi subsetova, dok je relativni odnos najzrelijih CD4TCRαβhi i CD8TCRαβhi timocita ostao neizmenjen. U mladih adulta primena somatostatina, iako dovodi do smanjena zapremine i celularosti korteksa ne dovodi do promena u relativnoj masi timusa. Procenat DPTCRαβ-/hi timocita je bio smanjen, dok je procentualno učešće DNTCRαβhi timocita i obe jednostruko pozitivne subpopulacije (CD4TCRαβhi i CD8TCRαβhi, više CD8TCRαβhi) u ukupnom broju timocita bilo povećano. Navedeni rezultati ukazuju da SRIH-14 različito utiče na morfologiju timusa i na subpopulacije timocita pacova u zavisnosti od uzrasta tretiranih životinja.

AB  - The study was undertaken to explore whether there were: i) apart from neural and circulatory, some other sources of catecholamines (CAs) in rat thymus and ii) gender-specific differences in thymic CA levels, and if so to elucidate the role of sex steroids in this phenomenon. Tyrosine hydroxylase (TH) immunoreactivity was found in thymocytes and thymic epithelial cells (some of which showed morphological features of nurse cells). The density of CA-synthesizing cells was greater in male than in female rats. Noradrenaline (NA), but not dopamine (DA), was detected in thymocytes. NA and DA levels in thymi, and the NA level in thymocytes, were higher in male rats. To explore the Putative role of sex steroids in this dichotomy in the thymi of adult rats gonadectomized (Gx) or sham-Gx at the age of 30 days the density of TH+ cells and CA levels were measured. Gonadectomy abolished sexual dimorphism in the density of thymic TH+ cells (diminishing their density in male rats) and thymic CA levels (the NA levels were reduced in rats of both sexes and also the DA level in male rats). Therefore, it can be assumed that testicular and ovarian hormones control thymic NA and DA levels via different mechanisms. Moreover, in Gx rats, despite the decrease in the overall thymic NA level, an increase in the thymocyte NA level was found indicating that gonadal hormones exert differential effects on the NA level in distinct thymic cellular compartments.
