Regulation of herpes simplex virus-specific lymphoproliferation by suppressor cells

Regulation of herpes simplex virus-specific lymphoproliferation by suppressor cells.

We investigated the regulation of the herpes simplex virus (HSV)-specific lymphoproliferative response (LPR) by suppressor cells. The chief cell types in HSV-immune splenocytes proliferating in response to the antigen were Lyt 1+ and Lyt 2+ T cells, which accounted for approximately 60 and 40% of the response, respectively. Because the total responsiveness of splenocytes was enhanced after depl...

Macromolecular synthesis in cells infected with Herpes simplex virus

Production of soluble suppressor factors by herpes simplex virus-stimulated splenocytes from herpes simplex virus-immune mice.

Indirect evidence indicates that herpes simplex virus (HSV)-specific cytotoxic-T-lymphocyte induction is regulated by suppressor cells. To search for such suppressor effects, supernatant fluids from splenocyte cultures from normal and HSV-immune mice cultured either with or without viral stimulation were tested for their ability to inhibit HSV-specific cytotoxic-T-lymphocyte induction. Only the...

Different forms of membrane-associated herpes simplex virus glycoproteins induce functionally distinct subsets of herpes simplex virus-specific suppressor T cells.

Previous studies have shown that two types of virus-specific suppressor T cells (Ts) are induced in mice made tolerant with herpes simplex virus (HSV)-infected spleen cells (SC). One type of Ts blocks the afferent phase of the delayed hypersensitivity response to HSV (Ts-aff), and the other blocks the efferent or effector phase (Ts-eff). In this report we show that the induction requirements fo...

Herpes Simplex Virus and Langerhans Cell Histiocytosis

Background and objective: Langerhans cell histiocytosis (LCH) is a rare histiocytic proliferative disorder of unknown etiology and mainly affects young children. The histological feature is granuloma-like proliferation of langerhans-type dendritic cells. Although the possible role of viruses such as Epstein-Barr virus (EBV, Human Herpes virus -4</...
