Self-Boosting Vaccination In article number 2207892, Xiang Gao, Bo Liu, Jing and co-workers propose a pulsatile antigen released core-shell microparticle namely LbL/MPs to achieve self-boosting vaccination after single-injection simulate multi-injection immunization. show multiple release characteristics can effectively induce immune response. The microstructure supplies the characteristic of p...
In patients undergoing chemotherapy for the treatment of malignant disease, the reactivation of hepatitis B virus in hepatitis B surface antigen-positive patients has been frequently reported. However, activation has also been reported in hepatitis B surface antigen-negative patients who test positive for hepatitis B core antibody and/or hepatitis B surface antibody, who were thought to have ha...
دایورسیتی انتقال متعامد (مانند دایورسیتی در زمان و فرکانس) یکی از روش های ایجاد دایورسیتی در فرستنده می باشد که در سیستم هایی که تحت تاثیر فیدینگ چند مسیره قرار می گیرند بسیار کارآمد می باشد. اما در این روش? کارآمدی پهنای باند با افزایش تعداد شاخه های دایورسیتی کاهش می یابد و از این رو در سیستم های مخابرات بی سیم کمتر مورد توجه قرار گرفته است. اخیراً بیان شده است که با استفاده از نگاشت بیت های م...
Megakaryocytes develop from hematopoietic stem cells in the bone marrow via several sequential steps. During the promegakaryoblast stage, cell size and nuclear DNA ploidy increase by the process of endomitosis. The final differentiation stage of the maturation process is characterized by platelet release from the ends of long, thin cytoplasmic processes called proplatelets. In addition, platele...
Since both the liver and lung are derived from the endoderm, common antigens may appear on both tissues during malignant transformation. In an attempt to delineate cell surface alterations associated with the neoplastic transformation of these tissues, we have produced a library of monoclonal antibodies against a human hepatoma cell line termed FO CUS. One of these monoclonal antibodies, design...
Virus-specific CD8(+) T cells exert strong suppressive pressure on human/simian immunodeficiency virus (HIV/SIV) replication. These responses have been intensively examined in peripheral blood mononuclear cells (PBMCs) but not fully analyzed in lymph nodes (LNs), where interaction between CD8(+) T cells and HIV/SIV-infected cells occurs. Here, we investigated target antigen specificity of CD8(+...
This report presents a new and simple methodology for the synthesis of multicomponent peptide vaccines, named the peptide crosslinked micelles (PCMs). The PCMs are core shell micelles designed to deliver peptide antigens and immunostimulatory DNA to antigen-presenting cells (APCs). They are composed of immunostimulatory DNA, peptide antigen, and a thiopyridal derived poly(ethylene glycol)-polyl...
