Antigens of Toxoplasma gondii that provide specific and strong delayed type hypersensitivity (DTH) immune response, or which stimulate IFN-y secretion, are used for testing subjects for infection. Any skin testing format may be adapted for testing for the delayed type hypersensitivity, including a patch, a needle, or a prong. Presence of DTH indicates infection. Alternate methods of detecting a T cell response including monitoring IFN-y secretion may be used.

There is provided a composition including parietal polysaccharides from at least one Candida species and parietal polysaccharides from at least one different yeast species. The composition can be used in modulating and/or stimulating immune responses in animal or human.

Provided herein are methods for detecting an Aspergillus protease in a sample, diagnosing a subject with aspergillosis caused by an Aspergillus infection based on the presence of an Aspergillus protease in a sample, and methods of aspergillosis treatment that incorporate these diagnostic methods. In certain embodiments, the Aspergillus protease is Asp f2, and the Aspergillus infection is caused A. fumigatus, A. flavus, A. versicolor, A. niger, or A. terreus. Also provided herein are antibodies and kits for use in these methods, including novel antibodies specific for Asp f2.

Provided herein is an antibody as well as chimeric antigen receptor (CAR) to the Aspergillus antigen p60-binding domain. Further provided herein are immune cells expressing the CARs as well as methods of their use in the treatment of fungal infections and cancer.

Provided herein are compositions of trehalose phospholipids and uses thereof, e.g., compounds and compositions comprising 6,6′-diphosphatidyltrehalose (diPT) and analogs thereof with modifications of the diPT chemical scaffold, that bind and agonize Mincle, and the use thereof as adjuvants.

The present disclosure provides vaccine compositions comprising at least one adjuvant and at least one antigen, wherein the adjuvant is a cationic lipid. The disclosure also provides methods of treating a disease in a mammal, methods of preventing a disease in a mammal, and methods of effecting antigen cross presentation to induce a humoral immune response and a cellular immune response in a mammal utilizing the vaccine compositions. Cross presentation of various antigens can be achieved by formulating the specific antigens with cationic lipids possessing adjuvant properties.

Materials and methods for detecting and treating Coccidioidomycosis (Valley Fever) are provided herein. For example, materials and methods for enriching and detecting biomarker antigens (e.g., polypeptides and/or glycans) from Coccidioides immitis and Coccidioides posadasii, the fungi that cause Valley Fever, are described herein, as are methods for treating an individual for Valley Fever based on the results of the described detection methods.

The disclosure relates to polypeptides and pharmaceutical compositions comprising polypeptides that find use in the prevention or treatment of cancer, in particular breast cancer, ovarian cancer and colorectal cancer. The disclosure also relates to methods of inducing a cytotoxic T cell response in a subject or treating cancer by administering pharmaceutical compositions comprising the peptides, and companion diagnostic methods of identifying subjects for treatment. The peptides comprise T cell epitopes that are immunogenic in a high percentage of patients.

The present invention relates to bioconjugates and labeled derivatives of the adducts formed by the reaction of patulin with benzene-1,2-dithiols or their salts. Said conjugates are suitable for the production of antibodies capable of recognizing the aforementioned patulin-(benzene-1,2-dithiols) adducts with high affinity and specificity. Likewise, the present invention also relates to the use of bioconjugates of patulin-(benzene-1,2-dithiols) adducts and of labeled derivatives thereof as assay antigens. Furthermore, the present invention also relates to immunochemical methods for the analysis of patulin, using the bioconjugates and labeled derivatives and antibodies of the invention, which include a previous step to quantitatively convert patulin into these adducts. This invention also provides a kit for analyzing patulin comprising a benzene-1,2-dithiol or its salts, antibodies against patulin-(benzene-1,2-dithiols) adducts, and assay antigens.
