Human herpesvirus 8 infects and replicates in primary cultures of activated B lymphocytes through DC-SIGN.
Human herpesvirus 8 (HHV-8) is the etiological agent of Kaposi's sarcoma, primary effusion lymphoma, and some forms of multicentric Castleman's disease. Although latent HHV-8 DNA can be detected in B cells from persons with these cancers, there is little information on the replication of HHV-8 in B cells. Indeed, B cells are relatively resistant to HHV-8 infection in vitro. We have recently sho...
متن کاملDC-SIGN is a receptor for human herpesvirus 8 on dendritic cells and macrophages.
Human herpesvirus 8 (HHV-8) causes Kaposi's sarcoma and pleural effusion lymphoma. In this study, we show that dendritic cell-specific ICAM-3 grabbing nonintegrin (DC-SIGN; CD209) is a receptor for HHV-8 infection of myeloid DCs and macrophages. DC-SIGN was required for virus attachment to these cells and DC-SIGN-expressing cell lines. HHV-8 binding and infection were blocked by anti-DC-SIGN mA...
متن کاملHuman DC-SIGN binds specific human milk glycans.
Human milk glycans (HMGs) are prebiotics, pathogen receptor decoys and regulators of host physiology and immune responses. Mechanistically, human lectins (glycan-binding proteins, hGBP) expressed by dendritic cells (DCs) are of major interest, as these cells directly contact HMGs. To explore such interactions, we screened many C-type lectins and sialic acid-binding immunoglobulin-like lectins (...
متن کاملGlycoprotein B switches conformation during murid herpesvirus 4 entry
Herpesviruses are ancient pathogens that infect all vertebrates. The most conserved component of their entry machinery is glycoprotein B (gB), yet how gB functions is unclear. A striking feature of the murid herpesvirus 4 (MuHV-4) gB is its resistance to neutralization. Here, we show by direct visualization of infected cells that the MuHV-4 gB changes its conformation between extracellular viri...
متن کاملThe glycoprotein B homologue of human herpesvirus 6.
The gene for the homologue of herpesvirus glycoprotein B (gB) has been identified in the genome of human herpesvirus 6 (HHV-6), strain U1102, and the nucleotide sequence was determined. The open reading frame encodes a protein of 830 amino acids (93.2K) with the characteristics of a transmembrane glycoprotein and close similarity to the gp58/116 complex of human cytomegalovirus (HCMV). Monoclon...
