Granulosa cells in ovarian follicles of rat, mouse, rabbit and hamster were studied by lanthanum tracer and freeze-fracture techniques. Abundant gap junctions exhibited striking intraspecific variation in size and pattern of particle aggregation. The smaller gap junctions showed close packing of the intramembranous A face particles. In large gap junctions,(More)
Foxp3(+) regulatory T cells (T reg cells) effectively suppress immunity, but it is not determined if antigen-induced T reg cells (iT reg cells) are able to persist under conditions of inflammation and to stably express the transcription factor Foxp3. We used spleen cells to stimulate the mixed leukocyte reaction (MLR) in the presence of transforming growth(More)
Transthyretin is a human protein capable of amyloid formation that is believed to cause several types of amyloid disease, depending on the sequence deposited. Previous studies have demonstrated that wild-type transthyretin (TTR), although quite stable, forms amyloid upon dissociation from its native tetrameric form into monomers with an altered(More)
Cytokines secreted from dendritic cells (DCs) play an important role in the regulation of T helper (Th) cell differentiation and activation into effector cells. Therefore, controlling cytokine secretion from DCs may potentially regulate Th differentiation/activation. DCs also induce de-novo generation of regulatory T cells (Treg) that modulate the immune(More)
