The aim of this study is to analyze the dynamics of the mouse cytomegalovirus (MCMV)-dendritic cell (DC) interaction. Immature and mature DCs derived from the mouse stem cell line factor-dependent cell Paterson mixed potential were infected with a recombinant MCMV expressing green fluorescent protein. Infection of immature DCs resulted in DC activation and… (More)
Since Kaposi's sarcoma associated herpesvirus (KSHV) establishes a persistent infection in human B cells, B cells are a critical compartment for viral pathogenesis. RTA, the replication and transcription activator of KSHV, can either directly bind to DNA or use cellular DNA binding factors including CBF1/CSL as DNA adaptors. In addition, the viral factors… (More)
During secondary immunoglobulin (Ig) diversification in vertebrates, the sequence of the variable region of Ig genes may be altered by templated or non-templated mechanisms. In both cases, cytidine deamination by activation-induced cytidine deaminase (AID) in the transcribed Ig loci leads to DNA lesions, which are repaired by conservative homologous… (More)
A supplementary mirror is described for the fundus camera easily permitting correct adjusting of the central and temporal regions of the ocular fundus.
