Virus infection of a cell generally evokes an immune response by the host to defeat the intruder in its effort. Many viruses have developed an array of strategies to evade or antagonize host antiviral responses. Kaposi's sarcoma-associated herpesvirus (KSHV) is demonstrated in this report to be able

Kaposi sarcoma-associated herpesvirus [KSHV, also known as human herpesvirus 8 (HHV-8)] is the most recently identified member of the human herpesvirus family. Kaposi sarcoma (KS), primary effusion lymphoma, and multicentric Castleman disease are all associated with KSHV infection. Although the

With the aim to develop novel antiviral agents against Kaposi's Sarcoma Herpesvirus (KSHV) we are targeting the latency-associated nuclear antigen (LANA). This protein plays an important role for the viral genome maintenance during latent infection. LANA has the ability to tether the viral genome to

Kaposi's sarcoma-associated herpesvirus (KSHV) causes several human cancers, such as Kaposi's sarcoma (KS) and primary effusion lymphoma (PEL). Current treatment options for KSHV infection and virus associated diseases are sometimes ineffective, therefore, more effectively antiviral agents are

OBJECTIVE To study the efficacy of high doses of beta-ser-interferon (recombinant human 17-serine beta-interferon) in patients with human immunodeficiency virus (HIV) infection and Kaposi sarcoma. METHODS A nonrandomized, controlled trial of two high-dose regimens of beta-ser-interferon administered

Kaposi's sarcoma-associated herpesvirus encodes numerous regulatory proteins capable of modulating viral and cellular gene expression and affecting host cell functions. K-bZIP, a leucine zipper-containing transcription factor encoded by ORFK8, is one such protein. During infection, transcription of

BACKGROUND Diagnosis of pancreatic cancer is usually made by endoscopic retrograde cholangiopancreatography (ERCP) and corresponding findings in computed tomography (CT) or magnetic resonance imaging. Kaposi's sarcoma, a frequent tumor in individuals with a late-stage HIV infection, can be located

Many murine tumor models associated with murine leukemia virus(es) (MuLV) have been successfully treated by passive administration of antiviral antibodies. There is a large body of virus-negative tumors, however, which are lowly antigenic and thus refractory to such approaches. Therefore, an

Viral invasion of a host cell triggers immune responses with both innate and adaptive components. The innate immune response involving the induction of type I interferons (alpha and beta interferons [IFN-α and -β]) constitutes the first line of antiviral defenses. The type I IFNs signal the

OBJECTIVE Kaposi's sarcoma-associated herpesvirus (KSHV), or human herpesvirus 8, has been implicated as the causative agent of Kaposi's sarcoma. Retrospective studies show that the risk of development of Kaposi's sarcoma is significantly lower in AIDS patients who received ganciclovir or

OBJECTIVE To evaluate the association of ganciclovir (GCV) and foscarnet (PFA) therapy with the outcome of previously diagnosed Kaposi's sarcoma (KS) after initiating antiviral therapy for cytomegalovirus (CMV) end-organ disease. METHODS Retrospective study. METHODS KS progression was defined as a

Using a cell line (termed BCBL-1) derived from a peripheral effusion (body cavity-based) lymphoma latently infected with Kaposi's sarcoma-associated herpesvirus (KSHV), we recently reported the successful induction of KSHV replication in culture (Renne, R., W. Zhong, B. Herndier, M. McGrath, N.

BACKGROUND The antiviral protein Daxx acts as a restriction factor of avian sarcoma virus (ASV; Retroviridae) in mammalian cells by promoting epigenetic silencing of integrated proviral DNA. Although Daxx is encoded by a type I (α/β) interferon-stimulated gene, the requirement for Daxx in the

Kaposi's sarcoma-associated herpesvirus (KSHV) is an etiological agent of several AIDS-associated malignancies, including Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman's disease (MCD). Its lytic replication cycle has been proven to be critical for the

Noncoding RNAs have substantial effects in host-virus interactions. Circular RNAs (circRNAs) are novel single-stranded noncoding RNAs which can decoy other RNAs or RNA-binding proteins to inhibit their functions. The role of circRNAs is largely unknown in the context of Kaposi's sarcoma herpesvirus
