Special Issue Information

Dear Colleagues,

Viral Hemorrhagic Fever (VHF) is a group of acute zoonotic diseases with high mortality rates caused by seven different families of viruses that infect both humans and animals. These include the arenaviruses, bunyaviruses, filoviruses, and flaviviruses. It causes severe infections characterized by a hyperactive immune response that often leads to multiorgan failure and death. These diseases most commonly occur in tropical areas. Some viral hemorrhagic fevers are spread by mosquito or tick bites. The human immune system plays a crucial role in VHF pathogenesis. Studies have demonstrated that suppression of innate immunity can play a critical role in disease development as activation of the mononuclear phagocytic system can result in secretion of pathologic concentrations of cytokines and chemokines, and adaptive immune responses are potentially impaired by infected dendritic cells failing to undergo maturation. Ultimately, injury of the endothelium and coagulopathy are thought to be caused by inflammatory responses and uncontrolled viral replication. However, the specific molecular mechanisms contributing to disease process of VHF remain poorly understood.

In this special issue, we focus on the the host immune response has the potential to improve the diagnosis of viral hemorrhagic fevers and other diseases. It can also accelerate our efforts to understand the underlying molecular mechanisms that lead to pathogenesis and severe disease.

In this Special Issue, original research articles and reviews are welcome.

I/We look forward to receiving your contributions.

While several lines of evidence suggest a protective role of T cells against disease associated with Dengue virus (DENV) infection, their potential contribution to immunopathology in the acute phase of DENV infection remains controversial, and it has been hypothesized that the more severe form of the disease (dengue hemorrhagic fever, DHF) is associated with altered T cell responses. To address this question, we determined the transcriptomic profiles of DENV-specific CD8+ T cells in a cohort of 40 hospitalized dengue patients with either a milder form of the disease (dengue fever, DF) or a more severe disease form (dengue hemorrhagic fever, DHF). We found multiple transcriptomic signatures, one associated with DENV-specific interferon-gamma responding cells and two other gene signatures, one specifically associated with the acute phase and the other with the early convalescent phase. Additionally, we found no differences in quantity and quality of DENV-specific CD8+ T cells based on disease severity. Taken together with previous findings that did not detect altered DENV-specific CD4 T cell responses, the current analysis argues against alteration in DENV-specific T cell responses as being a correlate of immunopathology.
