A Novel AGR2 Variant Causing Aberrant Monomer-Dimer Equilibrium Leading to Severe Respiratory and Digestive Symptoms.

Anterior gradient 2 (AGR2) is a protein disulfide isomerase that is important for protein processing in the endoplasmic reticulum and is essential for mucin production in the digestive and respiratory tracts. Bi-allelic AGR2 variants were recently found to cause recurrent respiratory infections and failure to thrive with or without diarrhea (RIFTD; MIM # 620233), although the mechanisms behind this condition remain unclear. To date, at least 15 patients with homozygous AGR2 variants have been reported.

Regional variation in the organization and connectivity of the first synapse in the primate night vision pathway.

Sensitivity of primate daylight vision varies across the visual field. This is attributed to regional variations in cone photoreceptor density and synaptic connectivity of the underlying circuitry. In contrast, we have limited understanding of how synapse organization of the primate night vision pathway changes across space.

Tinidazole efficacy for amebic colitis therapeutic prophylaxis in patients with de novo acute leukemia receiving intensive chemotherapy.

Introduction: In Mexico, seroprevalence of Entamoeba histolytica is 8.4%. The intestinal amebiasis in patients with acute leukemia of novo, after the start of chemotherapy (CT) in the Hematology Service of the CMN 20 de Noviembre is 12%, even if patients show a negative baseline coprological test.

Corticotropin-releasing factor binding protein enters the regulated secretory pathway in neuroendocrine cells and cortical neurons.

Corticotropin releasing factor binding protein (CRF-BP) is a 37kDa glycoprotein that binds CRF with high affinity. CRF-BP controls CRF levels within plasma during human pregnancy. It has also been shown that CRF-BP is expressed in various brain nuclei.

Nocardia brasiliensis Modulates IFN-gamma, IL-10, and IL-12 cytokine production by macrophages from BALB/c Mice.

Interferon-gamma (IFN-gamma) is a critical cytokine involved in control of different infections. Actinomycetoma is a chronic infectious disease mainly caused by the bacterium Nocardia brasiliensis, which destroys subcutaneous tissue, including bone. Currently, the mechanism of pathogenesis in N.

Host immunity during RSV pathogenesis.

Infection by respiratory syncytial virus (RSV) is the leading cause of childhood hospitalization as well as a major health and economic burden worldwide. Unfortunately, RSV infection provides only limited immune protection to reinfection, mostly due to inadequate immunological memory, which leads to an exacerbated inflammatory response in the respiratory tract promoting airway damage during virus clearance. This exacerbated and inefficient immune-inflammatory response triggered by RSV, has often been attributed to the induction of a Th2-biased immunity specific for some of the RSV antigens.
