<br> The amino acid sequences of the V.sub.H CDR1s of ICOS.33 IgG1f S267E, 17C4, 9D5, 3E8, 1D7, and 2644 are shown in SEQ ID NOs: 9, 18, 26, 34, 42, and 191, respectively. The amino acid sequences of the V.sub.L CDR3s of ICOS.33 IgG1f S267E, 17C4, 9D5, 3E8, 1D7, and 2644 are shown in SEQ ID NOs: 15, 23, 31, 39, 51, and 196, respectively. Likewise, in some embodiments, when V.sub.L CDR sequences are mixed and matched, the CDR1, CDR2 and/or CDR3 sequence from a particular V.sub.L sequence preferably is replaced with a structurally similar CDR sequence(s). Examples of human IgG1 constant domains comprising mutations to enhance Fc.gamma.RIIb specificity are described herein and are also provided in the Sequence Listing. In some embodiments, anti-ICOS antibodies described herein exhibit increased agonist activity at least in part due to modifications that increased binding to, and/or specificity for, Fc.gamma.RIIb. See WO 2012/087928. Antibodies having enhanced specificity for binding to [http://www.dailymail.co.uk/home/search.html?sel=site&searchPhrase=inhibitory%20receptor inhibitory receptor] Fc.gamma.RIIb have lower A/I ratios.

Accordingly, also provided herein are anti-ICOS antibodies that have one or more methionine residues in the heavy and/or light chain CDRs replaced with amino acid residues that do not undergo oxidative degradation.<br><br><br><br> Antibodies interact with target antigens predominantly through amino acid residues that are located in the heavy and light chain CDRs. The mutations may be amino acid additions, deletions,  www.chaturbate token.com - [https://Xxxsexcom.com/ click here for more info] - or substitutions. Without intending to be limited by theory, FcR-mediated signal enhancement of agonist ICOS antibodies due to increased receptor clustering, or "cross-linking," of the present invention may be a major contributor to therapeutic efficacy. Such variants may also exhibit enhanced FcR-mediated cross-linking, resulting in enhanced therapeutic efficacy. Cross-linking of ICOS agonist antibodies by FcR engagement by the Fc portion of the antibody may increase signal strength and thereby enhance cell activation. In some instances, the resulting recombinant antibody has properties that are similar to the parental antibody. Mol. Immunol. 45:3926. P238D, V4, V7, V8, V9, V11 and V12 variants are described at Mimoto et al. SE and SELF variants are described at Chu et al. Such "back-mutated" antibodies are also encompassed in this disclosure.<br><br><br><br> In some embodiments, such agonistic anti-huICOS antibodies with enhanced Fc.gamma.RIIb-specificity exhibit superior efficacy in treating cancer. Given that each of these antibodies can bind to human ICOS, the V.sub.H and V.sub.L sequences can be "mixed and matched" to create other anti-huICOS binding molecules of the invention. For example, anti-huICOS antibodies that bind to the same or similar epitopes to the antibodies disclosed herein may be raised using immunization protocols, e.g., those described herein. Another type of variable region modification is to mutate amino acid residues within the CDR regions to improve one or more binding properties (e.g., affinity) of the antibody of interest. In another embodiment, the antigen-binding portion of the antibody binds to an epitope which comprises amino acid residues SIFDPPPFKVTL (SEQ ID NO: 203) of human ICOS. Other methods monitor the binding of the antibody to antigen fragments or mutated variations of the antigen where loss of binding due to an amino acid modification within the antigen sequence indicates the epitope component.<br>
