The subject relates to an isolated antibody that specifically binds to O25b antigen of multi drug resistant (MDR) E. coli strains, its medical and diagnostic use, method of producing the antibody, including an isolated nucleotide sequence, plasmids and host cells as used in the production of the antibody; and further an isolated epitope recognized the specific antibody.

The compound N-(4-{[4-amino-2-butyl-1H-imidazo[4,5-c]quinolin-1-yl]oxy}butyl)octadecanamide is a useful drug compound for enhancing immune response and can be used, for example, as a coronavirus vaccine adjuvant.

A method and an system for vaccinating a mammalian subject. The method includes the steps of: arranging a source of electromagnetic radiation proximate to a target zone of skin of the mammalian subject; controlling the source of electromagnetic radiation to deliver a dose of electromagnetic radiation to the target zone determined to create one or more thermally-denatured zones in the target zone; and intradermally injecting a vaccine within the target zone to vaccinate the mammalian subject. The system for vaccinating a subject may include an electromagnetic radiation source configured to be arranged proximate to a target zone on an exterior of the subject; a user control configured to selectively cause the electromagnetic radiation source to deliver a dose of electromagnetic radiation toward the target zone to create one or more thermally-denatured zones in the target zone; and a vaccine-delivery system configured to deliver a vaccine to the target zone.

The present invention includes composition and methods for composition for the oral delivery of a therapeutic agent that reduces, desensitizes, or prevents food, respiratory and other allergies. First pollen is cleaned to remove naturally-occurring allergic plant proteins to form a cleaned pollen and a therapeutically effective amount of an allergen is introduced into the cleaned pollen. The allergen-loaded cleaned pollen is delivered to a subject in need of therapy.

The present invention relates to a PD-L1 peptide fragment, useful in cancer therapies as well as PD-L1 peptide fragments for use in a method for treatment or prevention of a cancer, when administered simultaneously or sequentially with an additional cancer therapy.

Compositions and methods for enhancing antigen-specific immunity in a subject are provided. Pharmaceutical compositions including an effective amount of an immuno-stimulatory cardiolipin as an adjuvant in combination with an antigen and methods of use thereof for stimulating protective immunity to the antigen in a subject are provided. Administration of the combination of the antigen and cardiolipin adjuvant is effective to enhance antigen-specific immunity in a subject to a greater degree than administering to the subject the same amount of the antigen alone. The active agents can be administered together or separately. In preferred forms the cardiolipin is cardiolipin species (C18:2).sub.4. In preferred forms the antigen is formulated as a vaccine, such as an influenza vaccine. A preferred amount by weight of each reagent is about 10-40% cardiolipin to about 90-60% antigen(s), inclusive.

The present invention provides a compound of formula (I): ##STR00001##
or a pharmaceutically acceptable salt thereof, wherein R.sup.1, R.sup.2, m and n are as defined in the specification, with an inhibitory effect of PD-L1 expression and an inhibitory effect of reduced production of IL-2 and a medicament useful for the treatment of a disease associated with the reduced immune function caused by the formation of PD-1/PD-L1 binding.

Amphiphilic oligonucleotide conjugates that enhance adjuvant function are disclosed. The conjugates typically include: a lipophilic component, and conjugated thereto (directly or indirectly) an immunomodulating oligonucleotide that, if it were not conjugated to the lipophilic component, would suppress TLR7 and/or TLR8 stimulation. In the presence of albumin, these conjugates significantly enhance adjuvant function, in particular the function of TLR7/8-mediated adjuvants such as an imidazoquinolinamine. The conjugates can be administered, along with an adjuvant compound, to a subject in order to cause and/or enhance an immune response (for instance, to an infectious agent or a cancer antigen) in the subject.

Toll-like receptor (TLR) ligands having an allose-based core are stable in aqueous formulation and are useful in treating, preventing, or reducing susceptibility to diseases or conditions mediated by TLRs, such as cancer, infectious disease, allergy, autoimmune disease, sepsis, and ischemia reperfusion.

Methods and compositions for identifying tumor antigens of human lymphocytes, and for treating subjects having cancer, are provided herein.
