GM1 binding-deficient exotoxin is a potent noninflammatory broad spectrum intradermal immunoadjuvant.

Intradermal (i.d.) immunization is a promising route of vaccine administration.

Transcutaneous immunization and immunostimulant strategies: capitalizing on the immunocompetence of the skin.

The skin is an attractive target for vaccine delivery. Topical application of adjuvants results in potent immune responses and good safety profiles. Adjuvants can be coadministered in a patch with vaccine antigens (transcutaneous immunization) or similar delivery format, or administered separately with an injection or IS patch (Iomai), leading to enhanced immune responses.

Minimal reactivation of Kaposi's sarcoma-associated herpesvirus by corticosteroids in latently infected B cell lines.

Corticosteroid use in transplant recipients increases the incidence and severity of Kaposi's sarcoma (KS), a disease associated with KS-associated herpesvirus (KSHV) infection. Recently, the prototypic corticosteroid, hydrocortisone, was shown to directly induce lytic cycle reactivation of KSHV in latently-infected BCBL-1 cells. The purpose of this study was to examine this phenomenon in further detail.

Hypoxia induces lytic replication of Kaposi sarcoma-associated herpesvirus.

There is substantial evidence that Kaposi sarcoma-associated herpesvirus (KSHV) plays an important role in the pathogenesis of all forms of Kaposi sarcoma (KS). It has been noted that KS commonly occurs in locations, such as the feet, where tissue may be poorly oxygenated. On the basis of this observation, the potential role of hypoxia in the reactivation of KSHV replication was explored by studying 2 KSHV-infected primary effusion lymphoma B-cell lines (BC-3 and BCBL-1) latently infected with KSHV.

Targeted inhibition of calcineurin signaling blocks calcium-dependent reactivation of Kaposi sarcoma-associated herpesvirus.

Kaposi sarcoma-associated herpesvirus (KSHV) is associated with KS, primary effusion lymphoma (PEL), and multicentric Castleman disease. Reactivation of KSHV in latently infected cells and subsequent plasma viremia occur before the development of KS. Intracellular signaling pathways involved in KSHV reactivation were studied.
