For these reasons new IL2 biologics are needed having improved pharmacokinetics and durability of responses for use. More recently, lower doses of IL2 have been used to selectively boost tolerance to suppress unwanted immune responses associated with autoimmune-like attack of self tissues. FIG. 10 shows LC-MS/MS based analysis of (G3S)3 linker stability in IL2(21-153)-(G3S)3-CD25(22-212) in human or mouse serum in vitro. FIG. 3 shows serum concentration-time profiles of indicated fusion proteins in Balb/C mice following a 0.5 mg/kg single intravenous (IV) or subcutaneous (SC) dose. As used herein, "Interleukin-2", "IL2", or "IL-2" refers to any native or recombinant IL2 from any vertebrate source, including mammals such as primates (e.g., humans) and rodents (e.g., mice and rats), and domesticated or agricultural mammals unless otherwise indicated. IL2 and its receptor (IL2R) are required for T-cell proliferation and other fundamental functions which are crucial for the immune response. The presently disclosed subject matter generally relates to methods and compositions for modulating the immune response employing an Interleukin-2/Interleukin-2 Receptor-alpha fusion protein. In certain embodiments, the patient to be treated with one of the methods provided herein has developed drug resistance to the anticancer therapy.





In some embodiments, the methods disclosed herein further comprise administering to the subject a second agent. 111. The method of claim 110, wherein the second agent is a PD-1 antagonist, a CTLA-4 antagonist, a TIM3 antagonist, a GITR antagonist, a KIR antagonist, a LAG3 antagonist, or any combination thereof. In some embodiments, the second agent is a PD-1 antagonist, a CTLA-4 antagonist, a TIM3 antagonist, a GITR antagonist, a KIR antagonist, a LAG3 antagonist, or any combination thereof. 61. The fusion protein of any one of claims 1 to 60, further comprising a linker fused in frame between the first polypeptide and the second polypeptide. One of the highlights of Chatterbate is the number of FREE shows. The best way is to click here and see for yourself a huge number of various amateur models perform live right now in this moment. The higher the number the more tokens. In some embodiments, the cytokine inhibitor targets one or more of IL-6, IL-10, TGF-.beta., VEGF, IFN-.gamma., or any combination thereof. 72. The fusion protein of any one of claims 1 to 71, which is a monomer.



55. The fusion protein of any one of claims 47 to 54, wherein one of the substitutions is at amino acid C125. IL2R.alpha. (SEQ ID NO:7); and/or my cams (ii) the IL2 polypeptide has at least one fewer glycosylation compared to native IL2 (SEQ ID NO:2); and wherein the fusion protein has IL2 activity. Preclinical studies showed that low IL2R signaling selectively promoted key activities of Tregs but not T effector (Teff) cells and that treatment of mice with low levels of IL2 prevented autoimmunity. The experience thus far has been that this therapy is safe, with no indication of reactivation of auto-aggressive T cells, while Tregs increase in nearly all patients, which is often accompanied by clinical improvement. It is to be noted that the term "a" or "an" entity refers to one or more of that entity; for example, "a nucleotide sequence," is understood to represent one or more nucleotide sequences.
