Dengue: defining protective versus pathologic immunity.
Dengue is an expanding public health problem, and an effective vaccine remains elusive. This review discusses how the significant influence of sequential infection with different dengue virus serotypes on the severity of disease can be viewed in terms of beneficial and detrimental effects of heterologous immunity. A more complete understanding of these effects is likely to be critical for predi...
متن کاملSculpting humoral immunity through dengue vaccination to enhance protective immunity
Dengue viruses (DENV) are the most important mosquito transmitted viral pathogens infecting humans. DENV infection produces a spectrum of disease, most commonly causing a self-limiting flu-like illness known as dengue fever; yet with increased frequency, manifesting as life-threatening dengue hemorrhagic fever (DHF). Waning cross-protective immunity from any of the four dengue serotypes may enh...
متن کاملOptimal pathologic staging: defining stage II disease.
Tumor stage remains the most important determinant of prognosis in colorectal cancer and is the basis of all authoritative patient management guidelines. The pathologic assessment of stage II disease is especially critical because it may help to identify patients at additional risk for whom surgery alone may not be curative. Accurate analysis of regional lymph nodes, extent of tumor penetration...
متن کاملDengue virus infection elicits highly polarized CX3CR1+ cytotoxic CD4+ T cells associated with protective immunity.
Dengue virus (DENV) is a rapidly spreading pathogen with unusual pathogenesis, and correlates of protection from severe dengue disease and vaccine efficacy have not yet been established. Although DENV-specific CD8(+) T-cell responses have been extensively studied, the breadth and specificity of CD4(+) T-cell responses remains to be defined. Here we define HLA-restricted CD4(+) T-cell epitopes r...
متن کاملInfluence of Mast Cells on Dengue Protective Immunity and Immune Pathology
Mast cells (MCs) are sentinels for pathogens. They are situated in the skin and mucosae where pathogen encounter is common and surround blood vessels. MCs pre-store vasoactive mediators and cytokines in granules, such as histamine, heparin, proteases, and TNF [1]. Degranulation occurs virtually instantaneously after MC activation by certain pathogen-derived or endogenous products signifying inf...
