US Patent 11512122 IL-7-FC-fusion proteins

Provided herein are dimeric IL-7-Fc fusion proteins that include Fc domains and one or more IL-7s. Also provided herein are variant IL-7s with modifications to reduce heterogeneity and/or reduced affinity/potency. Such variant IL-7s are useful, for example, in the subject dimeric IL-7-Fc fusion proteins. The dimeric IL-7-Fc fusion proteins can be used for applications where increased IL-7 activity is useful, for example, for increasing the proliferation of lymphocyte populations in mounting an anti-tumor response in a subject in need thereof.
