When Less Is More: T Lymphocyte Populations with Restricted Antigen Receptor Diversity.

The article reports on findings of two research papers including one on T lymphocyte with restricted antigen receptor diversity by Masaru Taniguchi & others, and another on human cells by Steven Balk & colleagues. Topics include the effects of invariant natural killer T cells on immune system, use of denaturing gel electrophoresis, polymerase chain reaction, and cloning for sequencing two invariant T-cell receptor (TCR) rearrangements & discovery of lymphocytes with restricted TCR diversity.
