A Novel Function Of Plasmacytoid Dendritic Cells In Regulating Type 2 Immune Responses, Hannah Leigh Miller
A Novel Function Of Plasmacytoid Dendritic Cells In Regulating Type 2 Immune Responses, Hannah Leigh Miller
Arts & Sciences Electronic Theses and Dissertations
The generation of an allergic response is particularly perplexing, as the mucosal immune system is exposed to a myriad of antigens on a daily basis, the majority of which do not elicit inflammation. However, for the growing population of patients impacted by allergic diseases, there is a clear breakdown of normal tolerance to innocuous antigens, resulting in symptoms mediated by antigen specific T helper 2 (Th2) cells. In addition to their well-established role in early antiviral immunity via production of type I interferon, plasmacytoid dendritic cells (pDC) have been implicated in the generation of immune tolerance in a variety of …

Dendritic Cell Development And Function, Vivek Durai
Arts & Sciences Electronic Theses and Dissertations
Dendritic cells (DCs) are a group of immune cells that include both classical dendritic cells (cDCs) and plasmacytoid dendritic cells (pDCs). cDCs are further comprised of two distinct subsets, cDC1s and cDC2s, which play critical roles in the initiation of innate and adaptive immune responses. Understanding how these lineages develop and function is therefore paramount. All DCs require the receptor tyrosine kinase Flt3 and its ligand Flt3L for their development, but the loss of Flt3L in mice leads to a more severe DC deficiency than does the loss of Flt3. This has led to speculation that Flt3L can bind to …

Understanding The Transcriptional Mechanisms Underlying Dendritic Cell Development, Prachi Bagadia
Arts & Sciences Electronic Theses and Dissertations
Dendritic cells (DCs) comprise an important immune lineage that plays a critical role in initiating and sustaining the proper immune response. They can be divided into two distinct branches, classical/conventional DCs (cDCs) or plasmacytoid DCs (pDCs). cDCs can further be classified as cDC1 or cDC2. Each DC subset exerts unique functions in vivo and are necessary for a complete immune response. The precise transcriptional programs underlying DC specification and commitment remain unclear. cDC1, cDC2, and pDC all arise from the common DC progenitor (CDP) in the bone marrow. How the CDP gives rise to all three DC subsets in an …
