Thymocytes, macrophages, and erythrocytes
Journal of Allergy and Clinical Immunology, 1974Abstract Lymphocyte-macrophage and lymphocyte erythrocyte interactions were examined in the 4 homologous and 12 heterologous combinations of mice, rats, guinea pigs, and rabbits. There was a highly species-specific interaction between thymic lymphocytes (T cells) and homologous peritoneal macrophages.

Renewal of thymocyte progenitors and emigration of thymocytes during avian development
Developmental & Comparative Immunology, 1998The avian thymus is colonized by three waves of hemopoietic progenitors during embryogenesis. An in vivo thymus reconstitution assay based on intrathymic injection of irradiated chicks showed that cells of para-aortic foci were able to differentiate into T lymphocytes, confirming their putative role in the first wave of thymus colonization.

The present study, through quantification of tyrosine hydroxylase (TH) expression and catecholamine (CA) content in the presence and in the absence of α-methyl-p-tyrosine (AMPT), a TH inhibitor, in adult thymic organ (ATOC) and thymocyte culture, demonstrated that thymic cells produce CAs.

In vivo stimulation of thymocyte proliferation by thymocyte growth peptide (TGP)
International Journal of Immunopharmacology, 1991Chromatographically pure thymocyte growth peptide (TGP) was injected into one of the two thymus lobes of guinea pigs. Pulse labelling of DNA-synthesizing cells was obtained by an intracardial injection of bromodeoxyuridine (BrdUrd). After 24 and 48 h, the frequency of labelled cells was increased in the TGP-treated lobe in comparison with the control ...

Thymocyte progenitors in ageing
Immunology Letters, 1994The effect of ageing on thymocyte progenitors in the bone marrow was studied in an in vitro experimental model that permits T lymphocyte development. The model is based on co-culture of BM cells from young and old mice with lymphoid depleted fetal thymus explants.

Abnormal Thymocyte Development and Neurofilament-Reactive Thymocytes in Thymoma
2000Myasthenia gravis (MG) is an autoimmune disease caused by autoantibodies against the acetylcholine receptor (AChR) at the neuromuscular junction [1, 2]. Mature CD4+ T-cells are involved in the production of these antibodies [3, 4]. The destruction at the neuromuscular endplates leads to the clinical symptom of muscle weakness.
