Multitasking in replication is common among geminiviruses.
Geminiviruses package single-stranded circular DNA and replicate via double-stranded DNA intermediates. During the past decade, increasing evidence has led to the general acceptance that their replication follows a rolling-circle replication mechanism like bacteriophages with single-stranded DNA. In a recent study, we showed that this is also true for Abutilon mosaic geminivirus (AbMV), but tha...
متن کاملEomesodermin-expressing T-helper cells are essential for chronic neuroinflammation
Development of acute experimental autoimmune encephalomyelitis (EAE) depends on Th17 cells expressing the nuclear factor NR4A2. However, in mice lacking NR4A2 in T cells, a late-onset disease is still inducible, despite a great reduction in acute inflammation. We here reveal that development of this late onset disease depends on cytotoxic T-cell-like CD4(+) T cells expressing the T-box transcri...
متن کاملDNA replication and cell cycle in plants: learning from geminiviruses.
Plant cell growth and development depend on continuous cell proliferation which is restricted to small regions of the plant called meristems. Infection by geminiviruses, small DNA viruses whose replicative cycle relies on host cell factors, is excluded from those proliferating areas. Since most of the replicative factors are present, almost exclusively, in proliferating cells, geminivirus infec...

Follicular Helper T Cells are Essential for the Elimination of Plasmodium Infection
CD4+ follicular helper T (Tfh) cells have been shown to be critical for the activation of germinal center (GC) B-cell responses. Similar to other infections, Plasmodium infection activates both GC as well as non-GC B cell responses. Here, we sought to explore whether Tfh cells and GC B cells are required to eliminate a Plasmodium infection. A CD4 T cell-targeted deletion of the gene that encode...
