摘要:
Methods for making an immunogenic conjugate that includes a hapten or an antigen covalently linked to a carrier. The methods include reacting a first agent with a dihydrazide resulting in a hydrazino-modified first agent, wherein the first agent is a hapten, an antigen or a carrier; reacting a second agent with a benzaldehyde compound resulting in a benzaldehyde-modified second agent, wherein the second agent is a hapten, an antigen or a carrier, provided that the first agent or the second agent is a carrier; and reacting the hydrazine-modified first agent with the benzaldehyde-modified second agent resulting in an immunogenic conjugate comprising a hapten or an antigen covalently linked to a carrier via a hydrazone linkage.

Immunogenic compositions and methods for eliciting an immune response against B. anthracis and other bacilli are provided that include immunogenic conjugates of a poly-γ-glutamic acid (γPGA) polypeptide of B. anthracis, or of another Bacillus that expresses a γPGA polypeptide. The γPGA conjugates elicit an effective immune response against B. anthracis, or against another Bacillus, in mammalian hosts to which the conjugates are administered.

摘要:
This invention pertains to methods for imaging the activity of extracellular proteases in cells using the anthrax binary toxin-system to target cells expressing extracellular proteases with mutant anthrax toxin protective antigens (μPrAg) that bind to receptors on the cells and are cleaved by a specific extracellular protease expressed by the cells, and ligands that specifically bind to the cleaved μPrAg and are linked to a moiety that is detectable by an imaging procedure. The μPrAg proteins used in the methods comprise a protease cleavage site that is cleaved by a specific extracellular protease and is in place of the furin cleavage site of the native PrAg. The methods are useful for diagnosing and treating diseases and undesirable physiological conditions correlated with the activity of extracellular proteases, and for optimizing the therapeutic efficacy of drugs used to treat such diseases and conditions.

摘要:
Novel compounds, pharmaceutical compositions, and methods are provided for modulating processes mediated by nuclear hormone receptors. A partial or complete agonist or antagonist modulates, directly or indirectly, an activity of one or more nuclear hormone receptors for glucocorticoids (GRs), androgens (ARs), mineralocorticoids (MRs), progestins (PRs), estrogens (ERs), thyroid hormones (TRs), vitamin D (VDRs), retinoids (RARs and RXRs), peroxisomes (XPARs and PPARs), icosanoids (IRs), or one or more orphan receptors, such as steroid and thyroid receptors. Exemplary compounds of the disclosure are bacterial products, for example bacterial toxins, and these compounds are useful in screens for other antagonists and agonists. Related methods and compositions are provided for diagnosis, treatment and prevention of bacterial disease and associated or unrelated inflammatory, autoimmune, toxic (including shock), and chronic and/or lethal sequelae associated with bacterial infection.
