t cell lymphoma
B lymphocyte (B Cell)
Individuals with both B-cell and T-cell deficiencies are said to have severe combined immune deficiency (SCID).
Helper T cell
T cells or T lymphocytes belong to a group of White blood cells known as Lymphocytes, and play a central role in cell-meaditated immunity . They can be distinguished from other lymphocyte types, suach as B cells and natural killer cells (NK cells) by the presence of a special receptor on their cell surface called T cell receptors (TCR). The abbreviation T, in T cell, stands for thymus, since this is the principal organ responsible for the T cell's maturation. Several different subsets of T cells have been discovered, each with a distinct function.

The first contact of a T or B cell with its specific antigen is called priming. It causes differentiation into effector T or B cells.

Thymus Lymphocytes could be roughly divided into two categories. B cell and T cell. Though they both originate from the bone marrow, T cell migrate to the" thymus," where it reach maturity while B cell got mature in the bone. That is, T stands for thymus. However, B doesn't mean "bone" actually, for B cell was first discovered in the "bursa of Fabricius" in a bird.
Where it is produced
Chemical messages called cytokines that are released by the t cell. These cytokines activate transcription factors that induce B cell proliferation.
