BACKGROUND Although there have been significant advances in understanding the basic pathogenesis of glioblastoma multiforme, the median survival of patients has changed little in the past 25 years. Recent studies have suggested that immune modulation through dendritic cell (DC) vaccines may stimulate the immune system against tumor antigens and potentially increase survival. OBJECTIVE To dete...

Functional genomics requires structural and functional studies of a large number of proteins. While the production of proteins through over-expression in cultured cells is a relatively routine procedure, the subsequent protein purification from the cell lysate often represents a significant challenge. The most direct way of protein purification from a cell lysate is affinity purification using ...

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....

background: adipose derived stem cells (ascs) provoke the accumulation and expansion of regulatory t cells, leading to the modulation of immune responses in tumor microenvironment. objective: to assess the effect of tumoral ascs on the trend of regulatory t cells differentiation. methods: peripheral blood naïve cd4+ t cells were co-cultured with ascs derived from breast cancer or normal breast ...

Dendritic cells (DCs) have been shown to be a promising adjuvant for inducing immunity to cancer. We evaluated tumor lysate-pulsed DC in a Phase I trial of pediatric patients with solid tumors. Children with relapsed solid malignancies who had failed standard therapies were eligible. The vaccine used immature DC (CD14-, CD80 , CD86 , CD83-, and HLA-DR ) generated from peripheral blood monocytes...

Telomerase is a crucial biomarker for cancers. Its reliable and sensitive detection, particularly in a single cell, has great significance for the early diagnosis of cancers, studies on tumor progression and anticancer therapy, which remain a challenge, due to nonspecific amplification. Herein, we developed a novel stem-loop primer-mediated exponential amplification (SPEA) strategy, which can s...
