Targeted subunit vaccines for cancer immunotherapy do not capture tumor antigenic complexity, and approaches employing tumor lysate are often limited by inefficient antigen uptake and presentation, and low immunogenicity. Here, whole cancer cells are processed to generate antigen-rich, membrane-enclosed subcellular particles, termed "reduced cancer cells", that reflect the diversity and breadth...

Background: Dendritic cells (DCs) contribute essentially to the outset and course of immune responses. So in patients with malignancy, there have been considerable interests in use of these cells in different interventions. Objective: To evaluate the impact of Leishmania major’s components on DC maturation and their use as a therapeutic agent against t...

We have reported previously that murine bone marrow-derived dendritic cells (DC) pulsed with whole tumor lysates can mediate potent antitumor immune responses both in vitro and in vivo. Because successful therapy was dependent on host immune T cells, we have now evaluated whether the systemic administration of the T cell stimulatory/growth promoting cytokine interleukin-2 (IL-2) could enhance t...

Cancer cell vaccines with strong specificity and low tolerance have been revealed to be a promising option for oncology treatment. Various antigen forms, including tumor cell lysate and glutaraldehyde-fixed tumor cells, have been intensively used in cancer vaccine preparation. However, the most effective antigen form has not yet been identified. In the present study, the antitumor efficiency of...

Single-cell RNA sequencing on circulating tumor cells (CTCs) proves useful to study mechanisms of heterogeneity, metastasis, and drug resistance. Currently, single-cell CTCs usually takes three prerequisite steps: enrichment from whole blood, characterization captured by immunostaining microscopic imaging, isolation through micromanipulation. However, multiple pipetting transferring steps can e...

Background A variety of autologous tumor/dendritic-cell (DC) vaccines have been pursued. Our prior autologous tumor/ DC fusion (dendritoma) vaccine demonstrated clinical benefit in metastatic melanoma; however, dendritoma production is difficult and not scalable for commercialization. We developed an alternative, novel approach to efficiently deliver the autologous tumor antigenic repertoire to...

leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. they produce testosterone leading to hyperandrogenism. we present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra sonography, and a rise of total and free serum testosterone. an ovarian source of androgen was suspected and a surgery performed. a diagnosis o...

background: bacterial dna has immunostimulatory effects on different types of immune cells such as dendritic cells (dcs). application of dcs as a cellular adjuvant represents a promising approach in the immunotherapy of infectious disease and cancers. objectives: to investigate the effect of tumor antigen pulsed dcs in the presence of cpg-1826 in treatment of a murine model of cancer. methods: ...

Background: Cell therapy and cell culture have received much attention in recent decades. Suitable cell growth requires growth supplements such as fetal bovine serum (FBS). FBS is component rich in nutrients, growth factors and supplementary compounds. However, FBS utilization has some limitations including mass production. Therefore, finding alternatives with the same growth promoting effects ...
