Preservation of immune repertoire by selective depletion of haploidentical grafts

Abstract

An important barrier to the success of transplanting haploidentical hematopoietic stem cells is delayed reconstitution of immune cells that provide protection from opportunistic infections and recurrent malignancy. In recent years a large research effort has been directed toward improving immune reconstitution through methods that potentially spare these cells while simultaneously reducing the alloreactive lymphocytes that cause graft-vs.-host disease. The basic concepts that support three very different approaches to selective depletion of haploidentical grafts are described in this section. Two methods take advantage of the proliferation of donor T cells after encountering alloantigen, and the third method exploits newer technology to engineer a graft that excludes alloreactive T cells while preserving other immunomodulatory cells.

B-cell leukemia includes various types of lymphoid leukemia that affect B cells. Here is the latest research on B-cell leukemia.

Cell Adhesion Molecules in the Brain

Cell adhesion molecules found on cell surface help cells bind with other cells or the extracellular matrix to maintain structure and function. Here is the latest research on their role in the brain.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

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.
