In vivo kinetics of GITR and GITR ligand expression and their functional significance in regulating viral immunopathology.
This report evaluates the role of interaction between glucocorticoid-induced tumor necrosis factor receptor (GITR) and GITR ligand (GITR-L) in the immuno-inflammatory response to infection with herpes simplex virus (HSV). Both GITR and GITR-L were transiently upregulated after ocular HSV infection, on antigen-specific T cells and antigen-presenting cells, respectively, in the draining lymph nod...
متن کاملInnate recognition network driving herpes simplex virus-induced corneal immunopathology: role of the toll pathway in early inflammatory events in stromal keratitis.
Ocular infection with herpes simplex virus (HSV) sets off an array of events that succeed in clearing virus from the cornea but leaves the tissue with a CD4(+) T-cell-orchestrated chronic inflammatory lesion that impairs vision. We demonstrate that Toll-like receptor (TLR) signaling forms a part of the recognition system that induces the syndrome that eventually culminates in immunopathology. A...
متن کاملThe Changing Epidemiology of Herpes Simplex Virus Type 1 Infection: The Associated Effects on the Incidence of Ocular Herpes
Herpes simplex virus type 1 (HSV-1) with a worldwide distribution has been reported in all human populations, resulting in a clinical spectrum of infections. Although HSV type 2 (HSV-2) is known as the most common cause of genital herpes, an increasing number of cases with genital herpes are caused by HSV-1. The present study aimed to discuss the changes in the epidemiology of HSV-1 infection i...
متن کاملControlling herpes simplex virus-induced ocular inflammatory lesions with the lipid-derived mediator resolvin E1.
Stromal keratitis (SK) is a chronic immunopathological lesion of the eye caused by HSV-1 infection and a common cause of blindness in humans. The inflammatory lesions are primarily perpetuated by neutrophils with the active participation of CD4(+) T cells. Therefore, targeting these immune cell types represents a potentially valuable form of therapy to reduce the severity of disease. Resolvin E...
متن کاملEvaluation of the Role of Herpes Simplex Virus Type 1 in the Secretion of Interleukin-1β (IL-1β) by Cultured Gingival Epithelial Cells
Background and Aims: Several studies have shown that there is greater number of viruses in deep periodontal pockets than in normal gingival sulcus. We also know that virus may have an important role in induction of Il-1β secretion by different human cells. In this study we intended to determine the capacity of Herpes simplex virus type 1 to stimulate Il-1β secretion in human gingival ...
