Abstract:
The present invention describes the design and development of new fibrinogen and fibrinogen derived products with significantly reduced binding to bacteria while retaining normal physiological functions by using modified fibrinogen amino acid sequences. The present invention describes modified sequences of Fg γ-chains and β-chains with reduced binding to S.aureus ClfA and S.epidermidis SdrG respectively. Modified Fg with the described modifications will not bind other bacterial surface proteins that bind Fg using similar mechanisms as ClfA and SdrG. These new Fg and Fg derived products will therefore have less binding to bacteria and will be advantageous compared to normal human Fg in a number of different settings.
Abstract:
Monoclonal and polyclonal antibodies are provided which recognize and bind to the SdrG protein of S. epidermidis , and more particularly to antibodies which recognize specific domains of the SdrG protein, namely the SdrG N1N2N3 protein (amino acids 50-597), the SdrG N2N3 protein (amino acids 273-597) and a truncated version of N2N3 identified as SdrG TR2 (amino, acids 273-577). The antibodies of the invention, as well as pharmaceutical compositions incorporating these antibodies, are particularly useful in treating or preventing infections caused by coagulase-negative staphylococci.

Abstract:
An Isolated lipase, designated GehD , from S. epidermidis has now been found to bind to collagen, and thus this protein may be used in methods of preventing or treating staphylococcal infections. The invention contemplates the use of compositions including GehD, vaccines containing GehD, and antibodies that can recognize GehD, and these are advantageously used with human or animal patients which may be susceptible to staphylococcal disease. In addition, medical instruments or biological implants can be treated using the collagen-binding protein of the invention in order to reduce or eliminate the possibility of their becoming infected or further spreading a staphylococcal infection.
Abstract:
The present invention includes a synthetic collagen that facilitates adhesion prevention and methods of use thereof. The present invention includes a prokaryotic collagen that facilitates adhesion prevention and treatment and methods of use thereof. The prokaryotic collagen includes an isolated and purified triple helical backbone protein that facilitates adhesion prevention: one or more alteration in a triple helical backbone protein sequence, and one or more binding motifs, wherein the isolated and purified triple helical backbone protein facilitates adhesion prevention.
Abstract:
Embodiments of the invention are directed to methods of treating, inhibiting or attenuating a microbial infection in an individual who has or is at risk for developing such an infection, comprising the step of administering an effective amount of a StIR polypeptide or peptide or fragment or derivative or analog thereof to the individual.
Abstract:
The present invention provides MSCRAMM® proteins from S. aureus which are putative highly-expressed antigens from methicillin-resistant S. aureus, including communit -associated MRSA (CA-MRSA), and these antigens can thus be utilized in methods of generating antibodies capable of binding these antigens which can be useful in methods of treating or preventing infection from MRSA. The present invention is directed to these proteins, antibodies capable of binding these proteins, methods of generating said antibodies, nucleic acids coding for said proteins, and pharmaceutical compositions or vaccines which include the proteins or antibodies of the present invention in combination with a pharmaceutically acceptable vehicle, carrier or excipient.
Abstract:
The Efb protein from Staphylococcus aureus has now been shown to have the ability to bind to the C3 protein which is a crucial component in the activation of complement, and a specific C3 binding region has been located at the C-terminal end of the Efb protein. Isolated proteins and protein fragments containing the Efb protein C3 binding region are thus provided which have complement inhibiting activity, and these proteins and fragments are particularly useful in therapeutic methods wherein the inhibition of complement is desirable, such as in the treatment of hemolytic anemia, the prevention of graft or implant rejection, and to alleviate complement activation that is associated with kidney dialysis methods such as hemodialysis.
Abstract:
Embodiments are directed to methods and compositions for modulating an immune response. In certain aspects the immune response is a type I hypersensitivity response. In particular aspects the subject has allergic asthma or allergic rhinitis. Using a conventional experimental asthma mouse model (BALB/c), the inventors demonstrate that aerosol administration of TLR agonists, in particular a combination of TLR2/6 and TLR9 agonist (e.g., TLR9 oligonucleotide agonist / PAM2CSK4) along with an antigen (e.g., ovalbumin (OVA)) suppresses the immune response as exemplified by the production of antigen-specific IgE and decreases the number of airway eosinophils in bronchoalveolar lavage fluid (BAL) in response to intraperitoneal (IP) immunization with an antigen mixed with alum.
