Dendritic cells (DCs) are potent antigenpresenting cells and have shown promise to function as “natural” vaccine adjuvants. Currently, most cancer vaccine trials using DCs generate autologous DCs ex vivo for each patient. Systemic treatment with Flt3 ligand (FL) results in a marked increase of DCs in tissues such as spleen and lymph nodes in mice and in the peripheral blood and skin of humans. ...

Nanocarriers have been explored to improve the delivery of tumor antigens to dendritic cells (DCs). Gold nanoparticles are attractive nanocarriers because they are inert, non-toxic, and can be readily endocytosed by DCs. Here, we designed novel gold-based nanovaccines (AuNVs) using a simple self-assembling bottom-up conjugation method to generate high-peptide density delivery and effective immu...

The recent identification of hepatitis B virus (HBV) epitopes restricted by multiple HLA alleles has greatly expanded the epitope repertoire available for T-cell-mediated therapeutic vaccine development. The HLA-B51-restricted peptide HBc19-27 is particularly interesting because it is located entirely within the HLA-A2-restricted HBc18-27 epitope. Here we show that HLA-B51-restricted cytotoxic ...

leishmaniasis is a major infectious disease of considerable public health in more than 86 countries around the world. several approaches toward vaccine development against this disease have been taken. glycoprotein (gp63) is conserved among diverse species of leishmania and has induced immunological responses in murine models. therefore, this glycoprotein has been considered as a second generat...

background permanent antigenic variation of influenza viruses causes a major concern to develop an effective human influenza vaccine. conserved antigens are new vaccine candidates because it is not necessary to match the prepared vaccine with circulating strains. ion channel m2 protein is conserved among all influenza a viruses, allowing the virus to enter host cells. objectives to prepare an e...

Posttransplant lymphoproliferative disorder (PTLD) and B cell lymphomas induced by EBV continue to be a major life-threatening complication in transplant patients. The establishment and enhancement of T cell immunity to EBV before transplantation and immunosuppressive therapy could help diminish these complications, but the lack of an effective vaccine has limited this prophylactic approach. We...

The passive application of Trastuzumab and Pertuzumab has demonstrated remarkable success in the clinical outcome patients with Her-2/neu positive metastatic breast cancer. However, active immunization mimotope/B cell epitope-based vaccines can induce production corresponding mAbs by patient’s immune system. We have developed a B peptide-based vaccine (HerVaxx) comprising Trastuzumab’s binding ...

Advances in machine learning have enabled the prediction of immune system responses to prophylactic and therapeutic vaccines. However, engineering task designing vaccines remains a challenge. In particular, genetic variability human makes it difficult design peptide that provide widespread immunity vaccinated populations. We introduce framework for evaluating uses probabilistic models, demonstr...

background: prostate cancer after lung cancer is the second cause of cancer-associated death in men. in recent years, targeted therapy of cancer has attracted researchers attention. the targeted therapy lead to decrease in side effects of drugs. studies have indicated that targeting peptides for cancer cells represent valuable tools for diagnostic and therapeutic. recently, phage display peptid...
