Lawrence Transfer Factor: Transference of Specific Immune Memory by Dialyzable Leukocyte Extract from a CD8+ T Cell...

Area of Science:

• Immunology
• Molecular Biology
• Biochemistry

Background:

• Dialyzable leukocyte extract (DLE), known as transfer factor (TF), facilitates antigen-specific cell-mediated immunity transfer.
• A recent study identified a DLE from a CD8+ T cell line that transfers antigen-specific immunity.

Purpose of the Study:

• To investigate the existence and potential applications of antigen-specific transfer factor (TF).
• To explore the biochemical composition of DLE for therapeutic development.

Main Methods:

• Analysis of a DLE derived from an established CD8+ T cell line.
• Biochemical characterization of the DLE components, including T cell receptor beta chain fragments, nucleotides, and proteins.
• Interviews with TF physician-scientists.

Main Results:

• A DLE capable of transferring antigen-specific immunity was isolated from a CD8+ T cell line.
• The DLE contains T cell receptor beta chain fragments and other molecular factors.
• Evidence suggests antigen-specific TF exists for a wide range of antigens.

Conclusions:

• Antigen-specific transfer factor (TF) is a viable immunological entity for most antigens.
• Modern biochemical approaches applied to CD8+ T cell line-derived DLE can identify therapeutic targets.
• Potential applications include treatments for infectious diseases, cancers, and autoimmune disorders.
