Egins with dengue infection of dendritic cells that, in turn, promiscuously activates T cells. T cells during a dengue infection have prolific and cross reactive effector functions in addition to producing copious amounts of cytokines that feature prominently in cases of DHF/DSS. A second component in immune enhancement is Antibody Dependant Enhancement (ADE). Heterologus non-neutralizing antibodi

Ls. Activation of effector T-cells and secretion of cytokines define a key development in course of disease associated with dengue virus infection. Four patient studies done in Vietnam[28], India[29], Cuba[30], and Brazil[31] all showed increases in INF, TNF, IL-10, IL-1, IL-6, IL-8, and MCP1 amongst a variety of other cytokines. In vitro studies, IFN, IL-6, TNF, and RANTES upregulation also have

Rough a time consuming and multiphase process that lasts anywhere from 6-24 hours. Adhesion molecules such as ICAM1 and ICAM3 are critical molecules generated by the T-cell during either phase and can bind to the adhesion molecules of DCs particularly DC-SIGN which is a known target of dengue. These molecules are necessary to form a stable synapse between the DC and T-cell[23]. T-cells, in turn, p

Fic T-cell response. The mechanism for this is unknown but given the intimacy between DCs and T-cells this represents a potentially productive field of research.The role of T cells in a dengue infectionThere is a clear consensus in the literature about activation of cross-reactive memory T-cells, independent of antibody enhancement, being a pivotal moment in the disease process. As compelling as A

Er positive cells were stained with Ki67, they show definitive proliferation. The cells are also found to be 'massively' apoptotic as determined by TUNEL staining. The balance of apoptotic cells with proliferative cells may skew T cell responses toward a crossreactive phenotype. When looking at the specific T-cells involved in secondary infections with DENV1, many of the T-cells show a preference

At typically binds to IgG and is composed of an chain for domain recognition, an ITAM (immunoreceptor tyrosine based activation motif), and a chain that is responsible for signal transduction. It is thought that IgM does not play a direct role in ADE and instead contributes to disease pathogenesis through activation of complement receptors[13]. IgM antibody enhancement was abrogated when C3R is
