Abstract: By introducing at least one cysteine residue based on wild-type IL-2, the binding plane of the IL-2 derivative and ? receptor subunit is partially or completely blocked, while the affinity of the IL-2 derivative to the complex of ? and ? receptor subunits is basically retained. A complex includes an IL-2 derivative, which is introduced with a third cysteine residue based on wild-type IL-2; and a blocking module, which has or is introduced with a fourth cysteine residue. The third cysteine residue on the IL-2 derivative and the fourth cysteine residue on the blocking module are capable of forming an intermolecular disulfide bond, thereby forming a complex of the IL-2 derivative and the blocking module. The binding plane of the IL-2 derivative and ? receptor subunit is partially or completely blocked, while the affinity of the IL-2 derivative to the complex of ? and ? receptor subunits is basically retained.

Abstract: The amino acid sequence of the present IL-15 analog includes the amino acid sequence of IL-15 and an amino acid sequence including at least one positively charged amino acid added to the C-terminal of the amino acid sequence of IL-15. The present IL-15 analog is highly expressed in Escherichia Coli, wherein the expression level is about 20-fold higher than that of the wild-type IL-15, and there is no significant difference in cell activity in vitro.

Abstract: The present disclosure discloses a client device having a digital signature. The client device includes processing circuitry configured to send a message to be stored in nodes after the nodes reach a consensus on the message. The message includes the digital signature of the client device. The processing circuitry obtains results from a subset of the nodes that receive the message. The results have respective digital signatures of the subset of the nodes. The nodes are in a first consensus mode for reaching the consensus on the message. After verifying the digital signatures, the processing circuitry determines whether one or more of the nodes has malfunctioned based on the results. Based on a determination that the one or more of the nodes has malfunctioned, the processing circuitry triggers the nodes to switch from the first consensus mode to a second consensus mode for reaching the consensus on the message.
