BCG (Bacillus Calmette Guerin) being a live attenuated vaccine may cause disseminated disease (BCGiosis) in patients with impaired immunity. Patients with severe combined immunodeficiency (SCID) having defect in both cellular and humoral immunity are predisposed to a host of live vaccine related complications, especially BCG. We report an infant presenting persistent fever, weight loss, anemia,...
Whether cytokines can modulate the fate of primitive hematopoietic progenitor cells (HPCs) through successive in vitro cell divisions has not been established. Single human marrow CD34+CD38-/lo cells in the G0 phase of cell cycle were cultured under 7 different cytokine combinations, monitored for proliferation on days 3, 5, and 7, then assayed for long-term culture-initiating cell (LTC-IC) fun...
Background—A T-cell–mediated inflammatory response occurs in the microcirculation during acute hypercholesterolemia. The objective of this study was to define the contribution of T-lymphocyte–derived interferon(IFN) to the leukocyte–endothelial cell adhesion induced by hypercholesterolemia. Methods and Results—Intravital videomicroscopy was used to quantify the adhesion and emigration of leukoc...
Schistosoma blood flukes, which cause schistosomiasis affecting 200 million people in the world, are dependent on signals from host CD4(+) T cells to facilitate parasite growth and development in the mammalian host and to induce Th2-biased inflammatory granulomas. B cells, however, are reported to down-regulate granulomatous pathology in schistosomiasis, but not to affect the development of blo...
Using the CRISPR/Cas9 gene-editing technology, we recently produced a number of rabbits with mutations in immune function genes, including FOXN1, PRKDC, RAG1, RAG2, and IL2RG. Seven founder knockout rabbits (F0) and three male IL2RG null (-/y) F1 animals demonstrated severe combined immunodeficiency (SCID), characterized by absence or pronounced hypoplasia of the thymus and splenic white pulp, ...
Crohn disease is a chronic inflammatory bowel disease of unknown etiology. Mycobacterium avium paratuberculosis (MAP) was found in the gut of patients with Crohn disease, but causality was not established. Fully developed, germ-free human small intestine and colon were established by subcutaneous transplantation of fetal gut into SCID (severe combined immunodeficiency) mice thereafter infected ...
In Manitoba, Canada, the overall incidence of Severe Combined Immunodeficiency (SCID) is three-fold higher than the national average, with SCID overrepresented in two population groups: Mennonites and First Nations of Northern Cree ancestries. T-cell receptor excision circle (TREC) assay is being used increasingly for neonatal screening for SCID in North America. However, the majority of SCID p...
