Embodiments of the methods, compositions, and systems provided herein relate to enzymatic enhancement of immunoassays using photonic sensor arrays.

The invention provides high-sensitivity methods for detection and quantification of target analytes in liquid samples (e.g., biological or environmental samples). The methods can be multiplexed to allow simultaneous detection and quantification of multiple target analytes that are contained in the same sample. The invention also provides related compositions and kits.

A fusion protein, which is characterized in that the fusion protein is composed by interleukin-2 (IL-2) being fused with and linked to an anti-human epithelial cell adhesion molecule (EpCAM) single-chain antibody. Further provided by the present solution is a use of the fusion protein in the preparation of a drug for treating tumors.

Provided herein is a method for measuring the levels of chronic inflammaging (SCI) of a subject. In some embodiments, the method may comprise measuring the amount of two or more of the proteins CXCL9, TRAIL, IFNG, EOTAXIN and GROA in a sample (e.g., blood serum) from the subject calculating a score based on the weighted amounts of each of those proteins.

De novo designed polypeptides that bind to IL-2 receptor .sub.c heterodimer (IL-2R.sub.c), IL-4 receptor .sub.c heterodimer (IL-4R.sub.c), or IL-13 receptor subunit (IL-13R) are disclosed, as are methods for using and designing the polypeptides.

De novo designed polypeptides that bind to IL-2 receptor .sub.c heterodimer (IL-2R.sub.c), IL-4 receptor .sub.cheterodimer (IL-4R.sub.c), or IL-13 receptor subunit (IL-13R) are disclosed, as are methods for using and designing the polypeptides.

The present invention includes methods and compositions for ameliorating symptoms or treating one or more adverse reactions triggered by infectious diseases or disease conditions that trigger a widespread release of cytokines in a subject comprising the steps of: identifying the subject in need of amelioration of symptoms or treatment of the infectious diseases or disease conditions that trigger a widespread release of cytokines; and administering one or more pharmaceutical compositions comprising a therapeutically effective amount of a curcumin extract, curcuminoids or synthetic curcumin (S-curcumin) and derivatives thereof, or empty liposomes, dissolved or dispersed in a suitable aqueous or non-aqueous medium sufficient to reduce the level of cytokines in the host.
