>One of our PI's is using CD83 and CD86 to resolve immature from mature in

>From  the PROW web site which has much more info including references
>MAIN CELLULAR EXPRESSION OF CD83
>* Non-follicular dendritic cells
>* Circulating dendritic cells
>* Interdigitating dendritic cells within lymphoid tissues
>* Langerhan's cells
>* In vitro generated dendritic cells
>* Thymic dendritic cells
>* Weak reactivity with some lymphoblastoid cell lines and with some
>germinal center B cells in vivo
>
>MAIN CELLULAR EXPRESSION OF CD86
>* CD86 is expressed constitutively by interdigitating dendritic cells in T
>zones of secondary lymphoid organs and at lower levels by Langerhans cells
>and peripheral blood dendritic cells
>* It is expressed by memory B cells and germinal center B cells;
>centrocytes express more CD86 than centroblasts. Small sIgD+,IgM+ tonsil B
>cells do not express CD86 but can be induced to express high levels of this
>molecule on activation in vitro through their surface immunoglobulin, CD40,
>MHC class II molecules or by phorbol myristate acetate with ionomycin.
>These signals also up-regulate the expression of CD86 on memory B cells and
>GC B cells
>* CD86 has also been reported to be expressed at low levels by monocytes
>and this expression is increased by culture with g-interferon
>* Endothelial cells (Seino et al. 1995), and T cells activated by CD3
>ligation have also been reported to express CD86 (Das et al. 1995);
>* Many T cell clones express both CD86 and CD80

>Hope this helps. Best wishes!

>Hello everybody,
>does anyone know a specific marker (except CD1a) for Dendritic cells which
>express mature and immature DCs? I want to seperate Monocytes, makrophages
>and DC with FACS. Are there any differences  in expression between
>dendritic cells generated of CD34+progenitor cells, DC generated of
>Monocytes or DC of the skin?
>Thanks for your help.
