The invention includes compositions comprising a therapeutic agent that decreases the population of pathological CD4g13 T cells, g13Th1 or g13Th2, in a subject and compositions comprising a therapeutic agent that increases the population of protective CD4g13 T cells, g13Th1 or g13Th2, in a subject. The invention also includes methods for treating an inflammatory or autoimmune disease in a subject by administering to the subject an effective amount of a therapeutic agent that increases the population of protective CD4g13 T cells, methods for detecting a protective or pathological immune response and methods for stimulating a protective CD4g13 T cell-mediated immune response to a cell population or a local tissue or organ in a subject in need thereof. The invention further includes a kit for diagnosing a pathological or protective g13Th1 or g13Th2 T cell responses in a subject.

A minimally-invasive atopic dermatitis test method comprises the steps of: applying, to the skin of a subject, a microneedle patch including a plurality of microneedles made of a biodegradable hyaluronic acid polymer and having a solid core structure and a bottom layer which is a base on which the plurality of microneedles are formed; maintaining the microneedle patch attached to the skin of the subject for a predetermined time; separating the microneedle patch from the skin of the subject after a predetermined time has passed to input the microneedle patch to a quantitative test; reading the amount of interleukin-4 and interleukin-13 adsorbed onto the surface of the microneedles of the microneedle patch in the quantitative test step; and evaluating atopic dermatitis activity on the basis of the reading of the amount of interleukin-4 and interleukin-13.

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

The subject invention pertains to systems and methods diagnosing, monitoring and treating women for successful embryo implantation and establishment of pregnancy using peripheral blood cytokine profiling and administration of immune-modulators to establish an implantation-promoting microenvironment in the uterus.

Disclosed are methods for methods for quantitating and standardizing an anti-inflammatory response of a product and methods for determining the likelihood that a product would produce an anti-inflammatory effect in a subject when administered to the subject. Accordingly, disclosed herein are methods, compositions and kits for characterizing and evaluating the anti-inflammatory effect of products, particularly therapeutic biological products.

Disclosed herein are methods for determining a concentration of at least one low concentration protein and at least one high concentration protein in a biological sample.

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

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.

Methods for treating a central nervous system (CNS) tumor in a subject, comprising administering to the subject MD-NA55 in combination with a vascular endothelial growth factor A (VEGF-A) inhibitor administered at a subtherapeutic level.
