Effects of photoperiod on structure of lamina propria of the testis of Octodon degus
(1995)
The changes occurring in the testicular lamina propria (LP) of the seasonal breeder Octodon degus were analyzed. Four groups of animals were studied using electron microscopic procedures. The animals in group I were ...
Increased production of soluble TLR2 by lamina propria mononuclear cells from ulcerative colitis patients
(2012)
Toll-like receptor 2 (TLR2) is a type I pattern recognition receptor that has been shown to participate in intestinal homeostasis. Its increased expression in the lamina propria has been associated with the pathogenesis ...
Inherent immune cell variation within colonic segments presents challenges for clinical trial design
(Oxford University Press, 2020)
Background and Aims: Intestinal biopsy sampling during IBD trials represents a valuable adjunct strategy for understanding drug responses at the tissue level. Given the length and distinctive embryonic origins of the ...
Local and systemic liberation of cytokines in ulcerative colltis
(1997)
Determination of plasmatic and tissular cytokine concentrations in inflammatory bowel diseases have frequently resulted in conflicting data. The aim of this study is to determine, in patients with ucerative colitis (UC), ...
An update on the pathogenesis of celiac disease Enfermedad celíaca y su patogenia
(2009)
Celiac disease (CD), with a 1% world-wide prevalence, is an enteropathy caused by an autoimmune reaction to gluten in genetically susceptible individuals, that codify for histocompatibility molecules HLA DQ-2/DQ-8. From ...
All-trans retinoic acid mediates enhanced T reg cell growth, differentiation, and gut homing in the face of high levels of co-stimulation
(2007)
We demonstrate that all-trans retinoic acid (RA) induces Ill adaptive T regulatory cells (A-Tregs) to acquire a gut-homing phenotype (alpha 4 beta 7(+) CC chemokine receptor 9(+)) and the capacity to home to the lamina ...
All-trans retinoic acid mediates enhanced T reg cell growth, differentiation, and gut homing in the face of high levels of co-stimulation
(ROCKEFELLER UNIV PRESS, 2007-06-25)
We demonstrate that all-trans retinoic acid (RA) induces FoxP3 adaptive T regulatory
cells (A-Tregs) to acquire a gut-homing phenotype ( 4 7 CC chemokine receptor 9 )
and the capacity to home to the lamina ...
Distribution of keratins, vimentin, and actin in the testis of two South American camelids: Vicuna (Vicugna vicugna) and Llama (Lama glama). An immunohistochemical study
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 1999-03-01)
The purpose of the present study was to investigate the pattern of distribution of cytokeratins, vimentin and muscular actin in the testis of vicuna (Vicugna vicugna) and llama (Lama glama) two species of camelids native ...
Interacciones Epitelio-Mesenquimáticas en el Desarrollo Testicular
(Sociedad Chilena de Anatomía, 2017)
La espermatogénesis es un proceso continuo que se inicia durante el desarrollo embriofetal. Las relaciones auto,
para y yuxtacrinas indican la interdependencia de las células intersticiales (de Leydig) con las células ...
Purinergic Signaling as a Regulator of Th17 Cell Plasticity
(Public Library Science, 2016)
T helper type 17 (Th17) lymphocytes, characterized by the production of interleukin-17 and other pro-inflammatory cytokines, are present in intestinal lamina propria and have been described as important players driving ...
