Abstract

Recent years have witnessed the development of a variety of promising immunotherapies for treating patients with B-cell non-Hodgkin's lymphomas. Each B lymphocyte expresses an immunoglobulin molecule that is the product of a unique combination of gene segments. B cell malignancy arises from one original B lymphocyte, and therefore all the members of a given lymphoma tumor population have the same unique immunoglobulin, which can serve as a target for immune therapy. When the idiotype (Id), or unique portion, of each immunoglobulin is used as a vaccine, antibodies and T cells can be induced and each can cause rejection of the tumor by the host. This special opportunity for tumor specificity is accompanied by the challenge of constructing a different vaccine for each patient. The first clinical trial of Id vaccination for lymphoma was initiated at Stanford University in 1988. Tumor cells obtained from lymph node sampling were fused with a myeloma cell line to generate a "hybridoma" producing large quantities of idiotype protein. Purified Id protein was then chemically coupled to keyhole limpet hemocyanin (KLH) and emulsified in an "oil-in-water" type immunologic adjuvant. The initial trial included patients with low-grade, follic...Continue Reading

Cancer Vaccines

Cancer vaccines are vaccines that either treat existing cancer or prevent development of a cancer.

Avian Influenza: Innate Immune Adjuvant

Adjuvants systems that are added to vaccines against avian influenza have be explored to enhance the innate immune system response against the virus. Here is the latest research on avian influenza and the innate immune adjuvant.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
