Abstract: A modified interleukin-2 (IL-2) molecule is obtained by being subjected to a modification as follows: substituting a region in an IL-2 molecule that mediates the binding of the IL-2 molecule to interleukin-2 receptor alpha (IL2R?) with a region in an interleukin-15 (IL-15) molecule that mediates the binding of the IL-15 molecule to interleukin-15 receptor alpha (IL15R?). The region in the IL-15 molecule that mediates the binding of the IL-15 molecule to the IL15R? includes 9 or more amino acid residues. Furthermore, a protein heterodimer including the modified IL-2 molecule and IL15R? (a Sushi domain) or a variant thereof is provided. The modified IL-2 molecule and/or the protein heterodimer including the modified IL-2 significantly reduce(s) an affinity of IL2R? to greatly reduce its side effects in clinical treatment and is promising drug candidate.

Abstract: A connector, a frame device, and a connector assembly method. Some terminal modules in the connector provided in the present disclosure are removed, or some terminal pairs in the terminal module are removed, so that a quantity of terminal pairs included in the connector is reduced without changing an outline dimension of the connector, thereby ensuring an original docking capability of the connector. In addition, a serial connector may be formed based on different quantities of removed terminal modules or removed terminal pairs. In this way, in the frame device, a user may select a connector of a corresponding specification based on an actual specification of a board, instead of selecting connectors of a high specification uniformly.
