Abstract: 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.

Abstract: 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.

Abstract: Provided herein are compositions comprising one or more statins and one or more antiretroviral agents, as well as therapeutic or prophylactic treatment methods featuring such combinations. The described compositions and methods are beneficial for treating or preventing human immunodeficiency virus (HIV)-associated pulmonary arterial hypertension (PAH), related conditions, and the symptoms thereof.

Abstract: Described are immunogenic compositions comprising a non-naturally occurring pan-fungal Kex peptide, and methods of using such compositions for the treatment or prevention of infection and/or diseases associated with fungal pathogens (e.g., Pneumocystis, Aspergillus, Candida, or Cryptococcus) in the subject. Also provided are compositions and kits for detecting or quantifying the presence of antibodies directed against a non-naturally occurring pan-fungal Kex peptide in a subject.
