Abstract: The disclosure relates to the field of molecular biology, and in particular relates to the use of CXCL 14. According to the present invention, different antigen proteins are transferred to the surface of a DC cell by means of the chemotactic binding capacity of CXCL 14 and surface receptors of immune cells such as DC cells. A chemokine of CXCL14 can effectively induce the binding of an antigen molecule to a specific immune cell at the N-terminal of an antigen protein, such that the cross presentation effect of the antigen molecule is greatly enhanced, and CXCL14 can finally induce a stronger specific immune response of the antigen molecule.

Abstract: The chemotactic binding ability of CCL13 and an immune cell surface receptor such as DC cells is used to transport different antigenic proteins to the surface of the DC cells, the efficiency of phagocytosis, processing, and presentation of various antigenic proteins by the DC cells is improved, and the effect of preventing and treating related diseases of the antigenic proteins is enhanced. A T2 sequence is further added in an antigen, such that the immune effect can be enhanced.

Abstract: Consideration of Quality of Service is taken into account during the establishment of a sleep cycle in a mobile station providing real-time services. Upon the mobile station's identification of a need for a real-time service to enter into sleep mode, a request conveying that need is sent to the base station. The base station replies with a start frame number and other sleep parameters. Thereafter the mobile station enters sleep mode comprising sleep intervals interleaved with listening intervals. To prevent transmission packets from being buffered at the mobile station for an excessive period of time due to attempts to transmit packets to the base station during a sleep interval, the length of the sleep interval is set so as not to exceed the maximum latency value reflecting the QoS of the real-time service negotiated during establishment of the real-time services.

Abstract: A mobile device includes a communications protocol stack including a MAC layer and TCP layer separated by an IP layer. A cross-layer coordination module parallel to the communications protocol stack is coupled to both the MAC layer and TCP layer. The MAC layer generates a message sent to the cross-layer coordination module indicating that the mobile device is about to engage in a communications handover from a first base station to a second base station. The cross-layer coordination module passes handover information to the TCP layer so as to inform the TCP layer of the communications handover. If the mobile device is operating as a TCP sender, the TCP layer freezes its connection and state during the communications handover. If the mobile device is operating as a TCP receiver, the TCP layer sends a TCP ACK message to a TCP sender having an advertised window size set to a zero value so as to cause the TCP sender to freeze a connection and state during communications handover.
