Immunostimulatory Agent Evaluation: Lymphoid Tissue Extraction and Injection Route-Dependent Dendritic Cell Activation

Dendritic cell immunization route determines integrin expression and lymphoid and nonlymphoid tissue distribution of CD8 T cells.

Exogenous dendritic cells (bone marrow-derived dendritic cell (BMDC)) display restricted trafficking in vivo after injection into mice, but the route(s) by which they generate gut-homing effector cells is unclear. Mesenteric lymph nodes (LN) and spleen were differentially targeted by i.p. and i.v. administration of BMDC, respectively, whereas mediastinal LN were targeted by both routes. BMDC in...

Route of antigen delivery impacts the immunostimulatory activity of dendritic cell-based vaccines for hepatocellular carcinoma

BACKGROUND Dendritic cells (DC) are uniquely equipped to capture, process, and present antigens from their environment. The context in which an antigen is acquired by DC helps to dictate the subsequent immune response. Cancer vaccination promotes antitumor immunity by directing an immune response to antigens expressed by tumors. We have tested the tumor-associated antigen alpha-fetoprotein (AFP...

Dendritic Cell Immunization Route

T cell-dependent antitumor immunity mediated by secondary lymphoid tissue chemokine: augmentation of dendritic cell-based immunotherapy.

Secondary lymphoid tissue chemokine (SLC) is a CC chemokine that is selective in its recruitment of naive T cells and dendritic cells (DCs). In the lymph node, SLC is believed to play an important role in the initiation of an immune response by colocalizing naive T cells with DC-presenting antigen. Here, we used SLC as a treatment for tumors established from the poorly immunogenic B16 melanoma....

The role of VipAlbumin® as an immunostimulatory agent for controlling homeostasis and proliferation of lymphoid cells

VipAlbumin(®) is a supplement from snakehead fish (Ophiocephalus striatus) which has high content of albumin that is very important to develop new cells. The aims of this study were to know the effect of VipAlbumin(®) to cell proliferation, expression level of CD4(+)CD62L(+) T cell, regulatory T cell, and B220+ cell, and immunocompetent cell cycle. Cell isolated from spleen of pathogen free mic...
