The molecular pathways contributing to humoral-mediated allograft rejection are poorly defined. In this study, we assessed the role of the herpesvirus entry mediator/B- and T-lymphocyte attenuator （HVEM/BTLA） signalling pathway in the context of antibody-mediated allograft rejection. An experimental setting was designed to elucidate whether the blockade of HVEM/BTLA interactions could modulate de novo induction of host antidonor-specific antibodies during the course of graft rejection. To test this hypothesis, fully allogeneic major histocompatibility complex-mismatched skin grafts were transplanted onto the right flank of recipient mice that were treated with isotype control, anti-CD40L or modulatory antibodies of the HVEM/BTLA signalling pathway. The frequencies of CD4 T follicular helper （Tfh） cells （B220-, CD4＋ CXCR5＋ PD-lhigh）, extrafollicular helper cells （B220-, CD4＋ CXCR5- PD-1＋ and PD-1-） and germinal centre （GC） B cells （B220＋Fas＋ GL7＋） were analysed by flow cytometry in draining and non-draining lymph nodes at day 10 post transplantation during the acute phase of graft rejection. The host antidonor isotype-specific humoral immune response was also assessed. Whereas blockade of the CD40/CD40L pathway was highly effective in preventing the allogeneic humoral immune response, antibody-mediated blockade of the HVEM/BTLA-interacting pathway affected neither the expansion of Tfh cells nor the expansion of GC B cells. Consequently, the course of the host antidonor antibody-mediated response proceeded normally, without detectable evidence of impaired development. In summary, these data indicate that HVEM/BTLA interactions are dispensable for the formation of de novo host antidonor isotype-specific antibodies in transplantation.

Selective suspension of single layer graphene mechanochemically exfoliated from carbon nanofibres

引用

Nano Research 2014年第7期7卷 963-972页

作者： Antonio Esau del rio-CastilloI Cesar Merino Enrique Diez-Barra Ester Vazquez Departamento de Quimica Orgdnica Facultad de Ciencias y Tecnologfas Qufmicas-IRICA Universidad de Castilla-La Mancha 13071 Ciudad Real Spain Grupo Antolin Ingenieria S.A. Burgos E09007 Spain

This paper presents the first report of the successful ball-milling exfoliation of graphitic filaments (GANF® carbon nanofibres) into single layer graphene. The addition of small amounts of solvent during the milling process makes it possible to enhance the intercalation of the exfoliating agent (melamine) between the graphene layers, thus promoting exceptional exfoliation. Advantage has also been taken of the fact that the Hansen solubility parameters of graphene are different from those of carbon fibres, which allows single and few-layer graphene to be suspended in a particular solvent, thus discriminating them from poorly exfoliated carbon nanofibres.
