The present invention includes compositions, methods of making and using the compositions for modulating the immune response in a subject by providing a vaccine composition having a pollen or spore disposed in a pharmaceutical carrier for delivery to a subject, wherein the pollen or spore comprises multiple pores that connect an outer surface of the pollen/spore to an inner cavity and one or more antigens disposed on the outer surface, in the inner cavity, in the multiple pores, or a combination thereof, wherein the one or more antigens modulate an immune responses in the subject.

The invention provides stable coronavirus spike proteins. Immunogenic compositions comprising same and the methods of using these immunogenic compositions are also provided.

Disclosed herein are methods and compositions related to the treatment, prevention, and/or amelioration of cancer in a subject in need thereof. In particular aspects, the present technology relates to the use of poxviruses, including a recombinant modified vaccinia Ankara (MVA) virus or vaccinia virus with deletion of vaccinia host-range factor C7 (MVAΔC7L and VACVΔC7L, respectively), alone or in combination with immune checkpoint blocking agents, as an oncolytic and immunotherapeutic composition. In some embodiments, the technology of the present disclosure relates to a MVAΔC7L or VACVΔC7L virus further modified to express human Fms-like tyrosine kinase 3 ligand (Flt3L).

The present invention includes methods and compositions for enhancing the efficacy of SMCs in the treatment of cancer. In particular, the present invention includes methods and compositions for combination therapies that include an SMC and at least a second agent that stimulates one or more apoptotic or immune pathways. The second agent may be, e.g., an immunostimulatory compound or oncolytic virus.

The present invention aims to provide a humoral immunity induction-promoting composition and a vaccine pharmaceutical composition which can universally be used for inducing humoral immunity to various antigens and exert a high antibody production inducing effect. The present invention relates to a vaccine pharmaceutical composition for inducing humoral immunity containing an antigen and a humoral immunity induction promoter whose active ingredient is a thrombosis treatment drug.

A method of treating cancer in a subject is disclosed, the method comprising administration of an oncolytic herpes simplex virus and administration of lymphocyte cells modified to express a chimeric antigen receptor (CAR) or modified to express a T cell receptor (TCR).

The present invention provides attenuated P. multocida strains that elicit an immune response in animal P. multocida, compositions comprising said strains, methods of vaccination against P. multocida, and kits for use with such methods and compositions. The invention further provides novel, genetically-engineered mutations in P. multocida hyaD and nanPU genes, which are useful in the production of novel attenuated P. multocida bacterial strains.

The present disclosure provides an adjuvant that can boost the quantitative expansion of immune cells in vivo, and a combination comprising the adjuvant and immune cells. The present disclosure also provides a cascade booster system comprising the adjuvant and modified immune cells. The present disclosure also provides a treatment method using the adjuvant and the immune cells of the present disclosure.

The present disclosure provides a subunit vaccine of contagious caprine pleuropneumonia and preparation method and use thereof, belonging to the technical field of preparation of animal infectious disease vaccine. The combination of Mycoplasma capricolum subsp. capripneumoniae immunoproteins comprises Mycoplasma capricolum subsp. capripneumoniae immunoproteins A, B, C, D and E; the mass ratio of Mycoplasma capricolum subsp. capripneumoniae immunoproteins A, B, C, D and E is (0.5-1.5): (0.5-1.5): (0.5-1.5): (0.5-1.5): (0.5-1.5). The subunit vaccine of contagious caprine pleuropneumonia comprises the combination of Mycoplasma capricolum subsp. capripneumoniae immunoproteins and adjuvant; the subunit vaccine has the advantages of high safety, good immunization effect, high stability and minor adverse effects.

Methods and compositions for stimulating or inhibiting antigen-specific immune responses using surface-anchored complement split products are described heron.
