Difference between B Lymphocytes and T Lymphocytes (B cell vs T cell)

Lymphocytes are mononucleate, nongranular leukocytes of lymphoid tissue, participating in immunity. They are found in blood, lymph and lymphoid  tissues such as spleen, lymph nodes, tonsils, Peyer’s patches, appendix. etc. 

The lymphocytes are of two types. They are B lymphocytes and T lymphocytes.

Comparison of B and T cells  (B cell vs T cell)

B cells	T cells
Origin : Bone marrow in adults	Origin :Bone marrow in adults
Maturation : Lymphoid tissue or bone marrow; Bursa of Fabricius in birds	Maturation: Thymus
Longevity : Short (Few days to a week)	Longevity :Long (Months to years)
Complement receptors : Present	Complement receptors: Absent
Surface immunoglobulins :Present	Surface immunoglobulins :Absent
Proliferation : Proliferate upon antigenic stimulation, differentiate into plasma and memory cells	Proliferation : Proliferate upon antigenic stimulation
Type of immunity :  Humoral immunity	Type of immunity ;Cell mediated and humoral
Secretary product :Antibodies	Secretary product : Lymphokines
Distribution : High in spleen, lymph nodes, bone marrow and other lymphoid tissues, Low in blood	Distribution: High in blood, lymph and lymphoid tissue
Types and Functions Memory cells- along lived cell responsible for the anamnestic response. Plasma cell- a cell arising from a B cell that manufactures specific antibodies For more immunology notes For more immunology videos	Types and Functions Tc Cell- Lysis cells recognized as non self and parasite infected cells. TH cell- It is necessary for B cell activation by T-dependent antigens and T effector cell. T regulator cell- It develops into TH or Ts cells and control balance between enhancement and suppression of response to antigen. Ts cell: It blocks induction  and or/ activation of TH cells and B cells. It helps maintain tolerance. TD TH cell: It provides protection against infectious agents, mediates inflammation and activates macrophages in delayed type hypersensitivity Null cells- Lymphocytes that lacks surface cell markers.
