Combinatorial Single Cell Strategies for a Crohn's Disease Gut Cell Atlas

2019-10-09 09:21:41 | BioPortfolio


Inflammatory bowel disease (IBD), consisting of two major forms, Crohn's disease (CD) and ulcerative colitis, affects more than 1.6 million people in the United States alone. Despite current therapies, remission only occurs in approximately half of patients. The goal of study is to map single-cell spatial relationships across the spectrum of ileum/ascending colon from healthy control patients to uninvolved/quiescent and involved/active CD patients and assess for relationships between single-cell data and patient clinical data.

The investigators will utilize endoscopic mucosal biopsies and surgical resection specimens with rapid transfer of fresh tissue to the single-cell preparation for RNA-sequencing and use of tissues for RNA-fluorescence in situ hybridization and multiplex immunofluorescence. Along with machine learning image analysis and bioinformatics, this will generate a robust/detailed single-cell gut cell atlas (GCA) of ileo-colonic CD at all disease activities versus normal tissues. The study will also compare the results of endoscopic mucosal biopsies to those obtained from full thickness surgical specimens by utilizing the Cooperative Human Tissue Network (CHTN).

The investigators anticipate the GCA data will provide new insights into disease pathogenesis, leading to new therapeutic targets.

Medical and Biotech [MESH] Definitions

A chronic transmural inflammation that may involve any part of the DIGESTIVE TRACT from MOUTH to ANUS, mostly found in the ILEUM, the CECUM, and the COLON. In Crohn disease, the inflammation, extending through the intestinal wall from the MUCOSA to the serosa, is characteristically asymmetric and segmental. Epithelioid GRANULOMAS may be seen in some patients.

A condition characterized by persistent or recurrent labial enlargement, ORAL ULCER, and other orofacial manifestations in the absence of identifiable CROHN DISEASE; or SARCOIDOSIS. There is no consensus on whether orofacial granulomatosis is a distinct clinical disorder or an initial presentation of Crohn disease.

Development of a library collection, including the determination and coordination of selection policy, assessment of needs of users and potential users, collection use studies, collection evaluation, identification of collection needs, selection of materials, planning for resource sharing, collection maintenance and weeding, and budgeting.

The taking of a blood sample to determine its character as a whole, to identify levels of its component cells, chemicals, gases, or other constituents, to perform pathological examination, etc.

Laboratory processes prior to specimen analysis. These processes include study design, compliance of the subjects investigated, compliance in adherence to protocols, choice of specimens utilized and sample collection.
