Abstract: Processes for producing and purifying recombinant proteins are disclosed. In particular, the present disclosure provides processes of producing and purifying multi-subunit proteins expressed in yeast or filamentous fungal cells. The production and/or purification of such proteins are monitored for impurities, preferably using lectin binding assays, such that one or more process parameters may be adjusted to maximize the amount of desired recombinant protein and minimize the amount of glycosylated impurities. The processes can also be monitored for other undesired product-associated impurities, such as aggregates and nucleic acids. In exemplary embodiments, the recombinant proteins are multi-subunit proteins, such as antibodies, the host cell is a yeast, such as Pichia pastoris, and the glycosylated impurity is a glycovariant of the desired recombinant polypeptide, such as an N-linked and/or O-linked glycovariant.

In some embodiments, the methods include administering to a subject suffering from or susceptible to a brain condition an angiotensin (1-7) peptide via either an intravenous or subcutaneous route of administration.
Abstract: This invention demonstrates the formation of a novel polarized membrane lipid raft signaling module in neurons, in response to several diverse neurotoxic stimuli. This polarization occurs well before neurons commit to die, and is an early mechanism in death signaling. The formation of this signaling module is dependent on cholesterol for its formation and provides a mechanistic explanation for the protective effects of cholesterol depleting drugs in several non-neural models of cell death. As such, the formation of the signaling module lends itself as a novel screen for the identification of new drugs and therapeutics which would retard its formation and protect against neuronal injury and death.
Abstract: The object of the invention is a DNA vaccine, method of inducing the immune response, antibodies specifically recognizing the haemagglutinin H5 of an influenza virus and application of the DNA vaccine. According to the invention, one or two-fold immunization of hens with DNA vaccine containing a cDNA encoding the modified H5 haemagglutinin HA protein, i.e. with the deletion of the cleavage site between HA subunits (this provides for greater safety of the vaccines). Moreover, the encoding region of the HA is modified in such a way that protein production in the bird cells should achieve maximal yield. The main modification is codon optimization for the hens and deletion of the site of proteolytic cleavage between subunits HA1 and HA2.

Abstract: Disclosed herein are isolated immunogens including variant hepatitis B surface antigens (HBsAgs). In an example, a variant HBsAg includes a HBsAg with one or more transmembrane domains of the HBsAg replaced with a gp41 antigenic insert. The antigenic insert can include an antigenic polypeptide fragment of gp41 including the membrane proximal region of gp41 and a transmembrane membrane region of gp41. The replacement of a membrane spanning domain of HBsAg with a membrane spanning domain of gp41 anchors gp41 into HBsAg in virtually the identical orientation as on HIV virions and correctly orients the nearby MPR on the lipid layer. Thus, the disclosed variant HBsAgs display the neutralization-sensitive MPR in association with a lipid layer, while presenting it at the most immunogenic site on HBsAg. Also disclosed are uses of these variant HBsAgs, and nucleic acids encoding variant HBsAgs, such as to induce an immune response to HIV-1.
