Identification Of A Novel Cytokine Inducible Stat5 Phosphoserine Site (Ps193) That Positively Regulates Its Transcriptional Activity And Is Found Constitutively Activated In Certain Hematopoietic Cancers, Abhisek Mitra
Open Access Theses & Dissertations
Hematological malignancies such as leukemia and lymphoma, can develop from aberrant changes in the cell signaling molecules to drive their uncontrolled cellular proliferation and differentiation. Activation, maturation, expansion and differentiation of T cells are critically regulated by the dynamics of various transcription factors activated by a variety of cytokines. Additionally, multiple effector molecules that mediate these T cells dependent signals include the JAK (Janus Kinase)-STAT (Signal transducer and activator of transcription) cascade. These signaling proteins are activated in response to a broad array of cytokines. Constitutively activated JAKs and STATs have been described in several T cell malignancies. A growing …
The Interplay Between Host Cells And The Human Pathogen Trypanosoma Cruzi: Role Of Toll-Like Receptors, Lilian Lie Nohara
The Interplay Between Host Cells And The Human Pathogen Trypanosoma Cruzi: Role Of Toll-Like Receptors, Lilian Lie Nohara
Open Access Theses & Dissertations
The protozoan parasite Trypanosoma cruzi is the etiologic agent of Chagas disease, a neglected infectious disease that is becoming a world health concern. This obligate intracellular parasite employs a diversity of molecules and strategies to successfully invade a wide variety of mammalian cells and modulate host immune responses, which are essential features for completion of its life cycle in the host. The major plasma membrane antigens of T. cruzi infective trypomastigote forms are glycosylphosphatidylinositol (tGPI)-anchored mucin-like glycoproteins. Although previous studies demonstrated that the proinflammatory responses induced by tGPIs are mediated by Toll-like receptor (TLR) 2, the involvement of other TLRs …
