The development of more effective antituberculosis vaccines would contribute to the control of the global problem of infection with Mycobacterium tuberculosis (MTB). Recently, the highlighted importance of autophagy in the host immune response against MTB has attracted the attention of researchers. However, the vaccines targeted at autophagy remain to be(More)
BACKGROUND Toll-like receptor (TLR) ligands have been explored as vaccine adjuvants for tumor and virus immunotherapy, but few TLR ligands affecting schistosoma vaccines have been characterized. Previously, we developed a partially protective DNA vaccine encoding the 26-kDa glutathione S-transferase of Schistosoma japonicum (pVAX1-Sj26GST). (More)
CD4(+)CD25(+) regulatory T cells (Tregs) do not only influence self-antigen specific immune responses, but also dampen the protective effect induced by a number of vaccines. The impact of CD4(+)CD25(+) Tregs on vaccines against schistosomiasis, a neglected tropical disease that is a major public health concern, however, has not been examined. In this study,(More)
A system of novel nanoparticles of star-shaped cholic acid-core polylactide-d-α-tocopheryl polyethylene glycol 1000 succinate (CA-PLA-TPGS) block copolymer was developed for paclitaxel delivery for breast cancer treatment, which demonstrated superior in vitro and in vivo performance in comparison with paclitaxel-loaded poly(d,l-lactide-co-glycolide) (PLGA)(More)
Multidrug resistance (MDR) is a major hurdle to the success of cancer chemotherapy. Poloxamers have been shown to reverse MDR by inhibiting the P-glycoprotein (P-gp) pump. The objective of this research is to test the feasibility of docetaxel-loaded PLGA-TPGS/Poloxamer 235 nanoparticles to overcome MDR in docetaxel-resistant human breast cancer cell line.(More)
It is well known that the mammalian associate of Myc-1 (AMY-1) plays a significant role in spermatogenesis or cellular differentiation. A full-length complementary DNA (cDNA) encoding AMY-1 of Schistosoma japonicum (SjAMY-1) was identified and isolated from a cDNA library. The gene contained an open reading frame of 315 nucleotides, encoding 105 amino(More)
The mechanism underlying autophagy alteration by mycobacterium tuberculosis remains unclear. Our previous study shows LpqH, a lipoprotein of mycobacterium tuberculosis, can cause autophagosomes accumulation in murine macrophages. It is well known that SapM, another virulence factor, plays an important role in blocking phagosome-endosome fusion. However, the(More)
As the function of autophagy becomes evident in a number of diseases, including cancer and infection, it is crucial to construct macrophage cell lines with stable expression of the microtubule-associated protein light chain 3 (GFP-LC3). In this study, a mouse LC3 open-reading frame was amplified by RT-PCR, and cloned into(More)
BACKGROUND Amphotericin B (AMB) is a polyene antibiotic with broad spectrum antifungal activity, but its clinical toxicities and poor solubility limit the wide application of AMB in clinical practice. Recently, new drug-loaded nanoparticles (NPs) - diblock copolymer D-α-tocopheryl polyethylene glycol 1000 succinate-b-poly(ε-caprolactone-ran-glycolide)(More)
BACKGROUND/AIMS Inactivation of tumor suppressors like p53 and p73 plays an important role in cancer initiation. We explored the clinical significance of p53 and p73 expression in esophageal carcinoma, along with their correlation with clinicopathological parameters of tumors for potential use in clinical evaluation of this disease. METHODOLOGY In the(More)
