Hemocyanin (HMC) has been shown to participate in multiple roles of immune defence. In this study, we investigated the antiproliferative effect and underpinning mechanism of HMC from Litopenaeus vannamei in vitro. Sulforhodamine B (SRB) assay indicated that HMC could dramatically inhibit the growth of HeLa cells, but not 293T cells under the same conditions. Moreover, typical morphological feat...

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...

bacterial and viral triggers are suspected agents in the initial etiology of autoimmune diseases. there are some studies on the etiology of autoimmune disorders which have focused on streptococcal infection and a possible relation with microbial heat shock proteins (hsp) which show significant homology with human heat shock proteins. in addition, some serotypes of streptococci cross-react with ...

recombinant human interferon alpha 2a (rhifn α -2a) production and cell growth were monitored in a set of genetically modified e. coli strains (msd1519, msd1520, msd 1521, msd 1522, msd 1523) producing rhifn α -2a. the growth was followed at od 600 nm, changes in cell physiology were detected by pyrolysis mass spectrometry (pyms) of cell biomass and recombinant protein production was determined...

AIM The aim of this study is to investigate the Protein-Protein Interaction Network of Celiac Disease. BACKGROUND Celiac disease (CD) is an autoimmune disease with susceptibility of individuals to gluten of wheat, rye and barley. Understanding the molecular mechanisms and involved pathway may lead to the development of drug target discovery. The protein interaction network is one of the suppo...

  Background: Multiple Sclerosis (MS) with four different types is one of the well studied autoimmune diseases of the central nervous system. Generally, two-thirds of MS patients are females who are at risk of pregnancy-related complications. Inappropriate responses of mother’s immune system, such as antibody production against placental proteins, may lead to pregnancy-related disorders. The as...

objective: dendritic cells (dcs) are essential for the activation and polarization of t cells during an adaptive immune response. in this research we investigated the effect of the lymphoide dcs pulsed with heat-treated tumor lysate (htl) as a vaccine in tumor immunotherapy. materials and methods: the balb/c mice were injected subcutaneously in the right flank with wehi-164 fibrosarcoma cells ...

background: heat shock protein 70 (hsp70) is present in all organisms studied so far, and is a major immunogen in infections caused by pathogens including leishmania spp. objective: the aim of this study was to clone and express hsp70 from l. infantum strain mcan/ir/96/lon-49 and evaluate antibody response against hsp70 in visceral leishmaniasis (vl). methods: the l. infantum hsp70 gene segment...
