摘要:
This application relates generally to enhancing immune responses. Such immune responses may be elicited by vaccine administration. Compositions and methods for inducing or enhancing an immune response to an antigen are provided. The compositions and methods are useful for, among other things, vaccine formulation for therapeutic and prophylactic vaccination (immunization) and for production of useful antibodies (e.g., monoclonal antibodies for therapeutic or diagnostic use).
摘要:
The inventors have discovered that a CKβ8-1 truncation variant, CKβ8-1 (25-116), is a bifunctional ligand for two distinct GPCRs, chemokine receptor CCR1 and formyl peptide receptor like 1 (FPRL1). Hence, the inventors have discovered that, in addition to its functional activity on CCR1, CKβ8-1(25-116) is also a functional ligand for the GPCR receptor FPRL1 that is involved in inflammatory reactions and innate immunity by recruiting monocytes and neutrophils. In addition, the inventors have discovered an alternatively spliced exon of CKβ8-1, named SHAAGtide. SHAAGtide, along with its parent chemokine CKβ8-1 (25-116), is fully functional on both monocytes and neutrophils that are known to express FPRL1.This application relates generally to enhancing immune responses. Such immune responses may be elicited by vaccine administration. Compositions and methods for inducing or enhancing an immune response to an antigen are provided. The compositions and methods are useful for vaccine formulations for therapeutic and prophylactic use (immunization) and for production of antibodies.
摘要:
The invention provides methods, reagents and devices for analysis of receptor ligand interactions, determining the profile of receptor expression in cells and cell populations, and diagnostic and drug screening methods. The invention makes use of immobilized tethered ligand fusion proteins having a ligand domain, a stalk domain, and optionally an immobilization domain.
摘要:
Truncated chemokines lacking an N-terminal region that activate CCR1 and/or FPRL1 and compositions containing the truncated chemokines are provided. Methods of identifying agents that modulate CCR1 and/or FPRL1 activity either by modulating the production of the truncated chemokines or the ability of the truncated chemokines to activate CCR1 and/or FPRL1 are also disclosed. Methods using the truncated chemokines to inhibit or activate CCR1 and/or FPRL1 mediated biological activities are also disclosed.

摘要:
The present invention provides methods for identifying an agent that specifically binds and/or modulates one topology of a chemokine receptor but not a second topology of the receptor. Such agents are useful as therapeutics for diseases or conditions associated with a particular chemokine receptor topology. Moreover, the agents are useful for detecting a particular topology of a chemokine receptor, thereby diagnosing disease or predisposition for a disease. In addition, the agents are useful for identifying and isolating cells that express a particular topology of a chemokine receptor.
