In cancer immunotherapy, robust and efficient activation of cytotoxic CD8(+) T cell immune responses is a promising, but challenging task. Dendritic cells (DCs) are well-known professional antigen presenting cells that initiate and regulate antigen-specific cytotoxic CD8(+) T cells that kill their target cells directly as well as secrete IFN-γ, a cytokine(More)
Breast cancer remains as a challenging disease with high mortality in women. Increasing evidence points the importance of understanding a crosstalk between breast cancers and immune cells, but little is known about the effect of breast cancer-derived factors on the migratory properties of dendritic cells (DCs) and their consequent capability in inducing T(More)
According to current dogma, there is little or no ongoing neurogenesis in the fully developed adult enteric nervous system. This lack of neurogenesis leaves unanswered the question of how enteric neuronal populations are maintained in adult guts, given previous reports of ongoing neuronal death. Here, we confirm that despite ongoing neuronal cell loss(More)
Dendritic cells (DCs) are the most potent antigen-presenting cells that play a crucial role in the initiation of an immune response. As DC-based therapeutic applications is increasing, large-scale DC production is required for transplantation. Human umbilical cord blood (UCB) has been shown to contain a rare and precious population of hematopoietic stem(More)
Recent studies on T follicular helper (Tfh) cells have significantly advanced our understanding of T cell-dependent B cell responses. However, little is known about the early stage of Tfh cell commitment by dendritic cells (DCs), particularly by the conventional CD8α(+) and CD8α(-) DC subsets. We show that CD8α(-) DCs localized at the interfollicular zone(More)
This report presents a multilevel microfluidic platform for robust construction of hydrogel scaffold in microchannels and its application to three dimensional (3D) multicellular co-cultures and assays. A new rapid prototyping method based on soft lithography using multi-layered adhesive tapes is also introduced. We have successfully cultured MCF-7 breast(More)
