Herpesviruses are main sculptors of natural killer (NK) cell repertoires. While the ?-herpesvirus human cytomegalovirus (CMV) drives accumulation adaptive NKG2C-positive NK cells, ?-herpesvirus Epstein–Barr virus (EBV) expands early differentiated NKG2A-positive cells. cells support immunity by antibody-dependent cellular cytotoxicity, seem to preferentially target lytic EBV replicating B The i...
Primary pulmonary hypertension (PPH) and Castleman's disease (CD) are rare conditions infrequently encountered in clinical practice. In this paper, two patients diagnosed with both of these diseases are reported. The authors speculate that rather than being a chance occurrence, these conditions are linked by a common angio-proliferative mechanism. Therefore, an association between infection wit...
A 47-year-old heterosexual man with history of intravenous (IV) methamphetamine use presented to the Emergency Department dyspnea and raised lesions throughout his arms, legs, chest as depicted in Figure 1. Biopsy a right leg lesion demonstrated atypical vascular proliferation within dermis producing slit-like/irregular architecture consistent Kaposi sarcoma. Human herpesvirus 8 (HHV-8) stainin...
Cyclin D family members are cellular protooncogenes, and their viral homologues in the Kaposi's sarcoma-associated herpesvirus (KSHV, human herpesvirus type 8 [HHV-8]) and the closely related Herpesvirus saimiri have been implicated as putative cofactors of viral transformation and pathogenesis. KSHV is regularly found in Kaposi's sarcoma and in the primary effusion B cell lymphoma and Castlema...
Kaposi's sarcoma-associated herpesvirus (KSHV)/human herpesvirus 8, a virus that appears to be involved in the pathogenesis of Kaposi's sarcoma and primary effusion lymphomas, encodes a G protein-coupled receptor (KSHV-GPCR) that exhibits constitutive signaling. In this report, we show that two chemokines, interleukin 8 (IL-8) and growth-related protein-alpha, activate KSHV-GPCR over constituti...
