Provided herein are compositions and methods for targeted treatment of Aspergillus-associated diseases and disorders in mammals, such as diseases and disorders associated with Aspergillus infection.

This invention is directed to vaccine compositions and methods of using the same to prevent infection.

The present disclosure is directed to human monoclonal IgE antibodies, and IgG antibodies engineered therefrom. Such engineered antibodies can be used to blunt pathologic IgE responses in subjects, such as in the treatment or prevention of allergies.

Phycoerythrin (PE) and peptide:MHCII (p:MHCII) reactive monoclonal antibodies; methods to generate monoclonal antibodies including, for example, peptide:MHC (p:MHC) reactive monoclonal antibodies; compositions including monoclonal antibodies; and uses thereof.

The invention generally provides methods of treating or preventing infection and/or disease associated with different fungal pathogens in a subject in need, using an isolated antiserum generated against an immunogenic peptide of one fungal pathogen that contains antibodies that cross-protect the subject from infection and/or disease associated with one or more different fungal pathogens. The antiserum may be generated against a Kexin peptide derived from one of a Pneumocystis, Aspergillus, Candida, or Cryptococcus fungal pathogen. The resulting cross-protective, isolated antiserum may be used as a therapeutic for treating or protecting a subject who receives the antiserum against infection and/or disease associated with multiple fungal pathogens, in addition to the pathogen against which the antiserum is generated. Also provided are compositions and kits for detecting or quantifying the presence of antibodies directed against a Kex peptide of one, two, three, or more of Pneumocystis, Aspergillus, Candida, or Cryptococcus in a subject.

The invention generally provides methods of treating or preventing aspergillosis disease and/or its symptoms associated with infection by the Aspergillus pathogenic fungus. The methods involve administering an Aspergillus Kexin peptide, or a composition comprising an Aspergillus peptide, to a mammalian subject in need thereof, such as a subject afflicted with aspergillus, or a subject susceptible to or at risk of infection by Aspergillus and ensuing aspergillosis disease. In some aspects, the Aspergillus Kexin peptide is an A. fumigatus Kexin peptide. In some aspects, the mammalian subject is a human patient. In some aspects, the patient is immunosuppressed or immunocompromised. The Aspergillus Kexin peptide as immunogen or vaccine generates a potent and robust immune response, e.g., antibody response, in the immunized subject. The methods afford therapeutic and protective treatment against aspergillosis and its symptoms, as well as a reduction in the severity of aspergillosis in the treated subjects.
