Subtypes of thymic epithelial cells defined by neuroendocrine markers
Abstract. The study attempted to define characteristics of thymic epithelial cells within rat thymus based on the expression of neuroendocrine markers. Using an immunohistochemical approach, theExpand
Effects of galanin on proliferation and apoptosis of immature rat thymocytes.
Evidence indicates that some regulatory peptides (endothelins, cholecystokinin and VIP) are involved in the control of thymus growth, and we have investigated whether galanin may be included in thisExpand
Thymic nurse cells: Their functional ultrastructure
Thymic nurse cells are defined in vitro as multicellular complexes of epithelial cells and thymocytes. Although these structures have been implicated in the intrathymic differentiation of thymocytes,Expand

SummaryThymic nurse cell complexes (TNC-c), isolated from mouse thymuses at 1 and 2 h after i.v. injection of 6-(3H)thymidine, were analyzed in autoradiographs of semithin serial sections with regardExpand
Endothelin-1, acting via the A receptor subtype, stimulates thymocyte proliferation in the rat.
Endothelins (ETs) are a family of vasoactive peptides widely distributed in the body systems, where they carry out major autocrine/paracrine regulatory functions, acting through two main subtypes ofExpand
Characteristics of age-related changes in rat thymus: morphometric analysis and epithelial cell network in various thymic compartments
Structural alterations in thymuses of female rats during the first 2 years of life were evaluated by morphometric analysis and, then, correlated with organization of epithelial cells in variousExpand
Subpopulations of blood lymphocytes in patients with rheumatoid arthritis.
The peripheral blood lymphocyte subpopulations of 18 patients with rheumatoid arthritis were compared with those of 10 healthy donors using minor modifications of the mixed immunofluorescence andExpand

Aging involves morphological and functional alterations within the microenvironment of the thymus where heterogenous populations of thymic epithelial cells (TEC) play the main roles. The studiesExpand
Evidence for Less Irritation to the Peritoneal Membrane in Rats Dialyzed with Solutions Low in Glucose Degradation Products
Background Acidic pH and the presence of glucose degradation products (GDP) are believed to compromise the biocompatibility of peritoneal dialysis fluids (PDF). The present study examines the effectsExpand
Morphologic Aspects of Chronic Peritoneal Dialysis in a Rat Model
Objective We previously put forward an experimental model for evaluating peritoneal function in chronically dialyzed rats. In the present paper, we show the morphologic alterations detected byExpand
