Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte May 2017

Lymphoid Hematopoiesis And The Role Of B-Cells In Transgenic Mouse Model Of Sickle Cell Disease, Christina Cotte

University Scholar Projects

Sickle cell disease (SCD) has been shown to be associated with decreased baseline immunity and thus increased susceptibility to infection. I sought to discern possible causes of this by looking into the correlations between SCD and hematopoiesis, the immune system and the neuroendocrine system, and ultimately by conducting experiments surrounding the impaired immune system of SCD. These experiments focused on the potential causes and effects of the diminution of B-1a cells in the SCD spleen. Adoptive transfers, infections with Streptococcus pneumoniae, and histologic imaging were conducted to establish if the diminution of the B-1a cells in the SCD spleen is ...


Engineering A Fluorescent Protease Sensor For In Vivo Protein Detection, Thomas C. Kinard Jan 2017

Engineering A Fluorescent Protease Sensor For In Vivo Protein Detection, Thomas C. Kinard

Honors Scholar Theses

This report details the results of an ongoing project to engineer a mutant form of Red Fluorescent Protein (RFP) variant mCherry that acts as a real-time in vivo protease sensor. The sought-after mutant only becomes fluorescent when exposed to Tobacco Etch Virus (TEV) Protease, this system’s model protease. This will be accomplished via the insertion of the TEV Protease Recognition Site (TEV-PRS) in such a position that, before cleavage, will prevent the protein from folding to fluorescent conformation, but upon cleavage, will allow for fluorescent conformation to occur. The cylindrical structure of the protein, composed of beta-pleated sheets, contains ...
