Antibodies and processes for preparing the same
Provided herein are various processes for the improved production of antibody producing organisms, antibody producing tissues, antibody producing cells and antibodies. In certain embodiments, provided herein are methods for rapidly producing antibody producing organisms, tissues, cells and antibodies derived from humans, organisms, plants or cells that are genetically altered to over-express certain proteins.
1. A method of producing an antibody to a selected antigen comprising:
contacting a B-cell with (a) an exogenous or recombinant MYC fusion peptide that translocates into the nucleus of the B-cell and (b) the selected antigen; and
inducing the B-cell to produce the antibody to the selected antigen,
wherein the Myc fusion peptide comprises:
(a) an HIV Tat protein transduction domain sequence;
(b) a MYC polypeptide sequence having a biological activity of MYC; and
(c) at least two protein tags, wherein the protein tags comprise a 6-histidine tag and a V5 epitope tag.
2. The method of claim 1 , wherein the method is performed ex vivo.
3. The method of claim 1 , wherein the selected antigen is a self-antigen.
4. The method of claim 1 , wherein the selected antigen is selected from: BAFFR, NGFR, IL-2, IL-10, IL-17, RANTES, MIP1a, MIP-1b, MCP-1, MIP-4, CXCR3, CXCR4, CCR3, CCR5, CCR9, HIV Env, and Influenza Hemagglutinin.
5. The cell of claim 1 , wherein the protein transduction domain sequence and the MYC sequence are linked by one or more linkers, wherein the linker comprises at least one amino acid.
6. The method of claim 1 , wherein the Tat protein transduction domain sequence is selected from the group consisting of TAT [48-57] and TAT [57-48] .
7. The method of claim 6 , wherein the Tat protein transduction domain sequence is SEQ ID NO:6.
8. The method of claim 1 , wherein the MYC activity comprises regulating transcriptional activity of MYC-responsive genes.
9. The method of claim 1 , wherein the MYC activity comprises promoting cell viability, cell immortality, cell growth and/or cell proliferation.
10. The method of claim 1 , wherein the MYC activity comprises promoting antibody production of a B-cell.
11. The method of claim 1 , wherein the B-cell is a human B cell.
12. The method of claim 1 , wherein the B-cell is an anergic B-cell.
13. The method of claim 1 , wherein the B-cell expresses the selected antigen.
14. The method of claim 1 , wherein the selected antibody comprises a human antibody.
