Described herein are compounds for use in vaccine compositions which contain natural or synthetic carbohydrate antigens. Such vaccines may be highly immunologically active due to the conjugation with an immune-stimulating protein or with a monophosphorylated lipid A derivative, and may be self-adjuvanting due to the presence of a monophosphorylated lipid A derivative. Treatments for cancer and fungal and bacterial infections are described herein.

Adjuvants acting at the level of antigen presentation useful for stimulation of specific immunity against tumor endothelial cells. In one embodiment the invention teaches the use of activation of specific antigen presenting cell programs to selectively induce cytotoxic T cells and antibodies with complement activating ability while not evoking antigenic responses that potentially stimulate angiogenesis or growth of tumor endothelial cells. Specifically, the invention teaches selection and use of adjuvants that inhibit suppressive dendritic cell produced factors, surface bound and soluble, while stimulating activatory cytokines. Adjuvant means include innate activatory molecules, gene silencing means, alarmins, and other stimulatory means resembling “danger” signals.

The adjuvanted conjugate opioid vaccine described herein is a conjugate of a protein carrier and at least one opioid backbone component or hapten conjugated thereto, admixed with at least one adjuvant. Anti-opioid effects are demonstrated after administration of a vaccine made up of the CRM197 protein carrier linked to a FEN backbone, combined with adjuvants such as dmLT or LTA1.

The present disclosure includes a pharmaceutical composition for treating a cancer in an HLA-A*02:07, HLA-A*03:01, HLA-B*15:01, or HLA-B*27:05-positive subject comprising a WT1-derived cancer antigen peptide or a peptide conjugate containing the peptide.

The present disclosure provides methods of preparing heteroaryl-containing compounds, wherein an azide-alkyne cycloaddition is accelerated in the presence of lauryldimethylamine oxide (LDAO). The present disclosure further provides conjugates of polypeptides and antigens prepared using such methods.

Provided herein are methods for rational design of nicotine haptens. More particularly, provided herein are methods for designing, selecting, and synthesizing nicotine haptens and nicotine hapten conjugates. Also provided herein are novel nicotine haptens and methods for using nicotine haptens to treat nicotine addiction.

The present invention provides a method of determining the identity and/or amount of an anti-IL-31 antibody in a sample. Such a method includes incubating a sample comprising an anti-IL-31 antibody with at least one mimotope selected from a feline IL-31 mimotope, a canine IL-31 mimotope, a horse IL-31 mimotope, and a human IL-31 mimotope; and determining the identity and/or quantity of the anti-IL-31 in the sample.

Certain embodiments are directed to method for synthesizing and using glycoconjugates on the immunodominant epitope Galα(1,3)Galβ(3(1,4)GlcNAcα (Galα3LNα).

The present invention is in the field of pneumococcal capsular saccharide conjugate vaccines. Specifically, an immunogenic composition for infants is provided comprising a multivalent Streptococcus pneumoniae vaccine comprising 2 or more capsular saccharide conjugates from different serotypes, wherein the composition comprises a serotype 22F saccharide conjugate. Such a vaccine may be used in infant populations to reduce the incidence of elderly pneumococcal disease such as exacerbations of COPD and/or IPD.

The present invention relates to virus-like particles of plant virus Cucumber Mosaic Virus (CMV), and in particular to modified VLPs of CMV comprising Th cell epitopes, in particular universal Th cell epitopes. Furthermore, these modified VLPs serve as, preferably, vaccine platform, for generating immune responses, in particular antibody responses, against antigens linked to said modified VLPs. The presence of the Th cell epitopes, in particular universal Th cell epitopes, led to a further increase in the generated immune response.
