Abstract: The disclosure shows that inflammation in metabolic syndrome is augmented by a hitherto overlooked lock-and-key activation of the elastin receptor, a protein involved in vascular (blood vessel) inflammation and elastin repair, with the C-peptide, a small protein that is produced in a 1:1 ratio alongside with widely known insulin. The elastin receptor is the lock that is activated by a key motif of amino acids (PG-domain) found in C-peptide and in breakdown products (PG-domain-fragments) thereof. Until now, no one has ever discovered this lock-and-key interaction between the two, now providing novel inroads in diagnosis, prevention and development of novel compounds for treatment of metabolic syndrome, exploiting the finding that not only the normal keys of the elastin receptor (elastin peptides), but also the C-peptide, a peptide we produce together with insulin every time glucose rises in our blood after a meal, interacts in a lock-and-key mode with the elastin receptor.

Abstract: The present invention relates to a method for reducing the occurrence and/or severity of viral infections. The method embodies procedures for expanding HIV from the blood of HIV antibody negative donors and deriving a non-infectious virus particle product that is antigenic. The procedures for deriving the antigenic, non-infectious virus particle product are optimally designed to maintain the integrity of the envelope proteins while maximizing the depletion of capsid proteins and RNA. The resulting virus particle product, when introduced into humans or non-human animals, enables the production of antibodies that target the natural envelope macromolecular structure that is required for infectivity. The present invention can be applied to producing virus stocks from the blood of HIV-seronegative donors, for deriving non-infectious virus particles that retain intact envelope proteins, for producing anti-viral antibodies, and for administering anti-virus antibodies to patients.
