| The H5N1 subtype of the influenza virus is highly pathogenic and lethal to humans and animal. The necessity for the development of new vaccines with a broad spectrum of efficacy against this pathogen seems to be very crucial. One highly regarded solution to this problem is to design and production of recombinant vaccines using the conserved peptide of influenza viruses. A search of international databases yielded the peptide sequence of the M2e fragment of H5N1 viruses isolated from Iran, as well as a variety of conserved peptide sequences of fragments of HA1, HA2, NA and NP of other H5N1 viruses. These sequences were obtained for both MHC receptors in mice. Subsequently, these fragments, in conjunction with a PADRE sequence, were connected by bioinformatics to design a fusion epitopic construct. Subsequently, the construct was optimized for expression in E.coli BL21. Following the expression and purifications of the fusion epitopic construct, it was injected subcutaneously (SC) into the hindlimb muscles of 6–8 old week female BALB/c mice. Three weeks following the conclusion of the second immunization, the mice in both immunized and control groups were weighed and checked for any adverse effects at the injection sites. Subsequently, the mice were euthanized and blood was collected from their hearts to determine the total IgG antibody titer before and after immunization by ELISA. No evidence of local inflammation or complications was observed at the SC injection sites until the end of the experiment. Additionally, the autopsy of mice showed no bleeding or lesions in organs, particularly the liver and spleen. The mice exhibited no significant change in weight throughout the immunization period. The total IgG level, as determined by average OD value in the serum of immunized mice, was found to be five times higher (5.881 ng/ml) than that of the control group (1.143 ng/ml). The results demonstrated a highly significant IgG antibody response following SC administration of an immunogenic recombinant peptide in mice. | ||

Ideas for the future of science publishing
“A large portion of traditional academic publishing is unequal, exclusionary, unsustainable and opaque,” writes biologist Humberto Debat. This affects scientists from low-income areas in particular, he notes. He is one of a diverse group of 11 researchers asked by Nature Human Behavior to comment on the future of publishing. Preprints can reduce bias by cutting out the need for publication ‘success’, adds psychologist Charlotte Pennington. And neuroscientist J. Andrew Pruszynski suggests that “we should consider the idea that most papers do not need traditional peer review”. Nature Human Behavior | ||
