Disclosed are compositions comprising an IL-2:anti-IL-2 antibody (Ab) complex (IL-2C) and methods of using said N compositions for the treatment of microbial infections, autoimmune diseases, autoinflammatory diseases, or cancers as well the treatment of inflammatory conditions or reduction in inflammation caused by said microbial infections, autoimmune diseases, autoinflammatory diseases, or cancers.

Anti-IL-12/IL-23p40 antibodies, such as ustekinumab, are used in methods and compositions for safe and effective treatment of psoriasis, particularly moderate to severe chronic plaque psoriasis, in pediatric patients. The methods and compositions address a clear unmet medical need in this patient population.

Disclosed herein are compositions and methods for increasing the stability of recombinant nanobodies. Also disclosed herein are recombinant nanobodies comprising an IL-2 polypeptide that bind serum albumin and uses thereof for treating cancers.

An implantable or injectable scaffold comprising immunostimulatory compounds and a suppressor of regulatory T cell induction is provided for use in immunotherapy treatments, including the treatment of cancers and other tumors, in particular solid tumors including inoperable tumors, as well as for other applications of immune enhancement and/or suppression.

Provided herein are methods and devices related to inducing a population of self-renewing or senescent stem cells, to produce one or more beneficial factors for the treatment of a disease or disorder in an individual. Also provided are compositions and methods for inducing senescence, useful for inducing senescence in a population of stem cells, in order to produce one or more beneficial factors for the treatment of a disease or disorder in an individual. Methods and devices to control and customize the production of the beneficial factors for the requirements of a disease or disorder being treated are described. Also provided are factor production units for the production of the beneficial factors, and devices for the delivery of the beneficial factors to an individual in need.

This document relates to methods and materials for targeted expansion of immune effector (Eff) T cells. For example, a composition containing one or more amino acid chains (e.g., one or more single-chain antibody/cytokine fusion proteins (immunocytokines)) that can bind to a heterodimeric receptor including an interleukin-2 receptor-β (IL-2Rβ) polypeptide and a common gamma chain (γ.sub.c) polypeptide (e.g., an IL-2Rβ/γ.sub.c polypeptide complex) can be administered to a mammal to stimulate Effs within the mammal to activate an immune response in that mammal. In some cases, methods and materials that can be used to treat a mammal having a condition that can benefit from activating an immune response (e.g., a cancer and/or an infectious disease) are provided. For example, a composition containing one or more single-chain immunocytokines that can bind to an IL-2Rβ/γ.sub.c polypeptide complex can be administered to a mammal having a cancer and/or an infectious disease to treat the mammal.

The present invention relates to a methods for high throughput screening of epitopes that are involved in T cell activation.

Provided are an anti-IL-2 antibody, and an antigen-binding fragment thereof and the medical use thereof. Further provided are a complex (including a fusion protein) of the anti-IL-2 antibody, the antigen-binding fragment thereof and IL-2, and the use of the complex as a drug for treating autoimmune diseases and inflammatory diseases.

Provided herein are compositions comprising greater than about 100 mg/mL of an anti-TSLP antibody, a surfactant, proline, and a buffer comprising greater than about 100 mg/mL of an anti-TSLP antibody, a surfactant, proline, and a buffer. Methods for treating an inflammatory disease in a subject are further provided.

Described herein are engineered anti-IL-2 antibodies with modified amino acid sequences. The engineered antibodies would confer modified receptor binding specificity to an IL-2-anti-IL2 antibody complex, inhibiting the binding of IL-2 to CD25. The engineered anti-IL-2 antibodies would facilitate expansion of subsets of effector immune cells and decrease undesirable effects caused by IL-2. Thus, the engineered anti-IL-2 antibodies would be useful in treating disease such as cancer and infection.
