Differences Between B-Cells and T-Cells. T cells and B cells are the major cellular components of the adaptive immune response. T cells are involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity.

Adult T-cell leukemia v Purple verbena The image above shows a number of ‘flower cells’ that are pathognomonic of HTLV-1 induced adult T-cell leukemia. The cells are lymphocytes with very irregular shaped nuclei.HTLV-1 (Human T-Lymphotrophic Virus 1) was the first identified retrovirus. It was discovered in Japan where it is most prevalent Like HIV, transmission of HTLV-1 is believed to occur from infected mother to child during breastfeeding; by sexual contact; or through exposure to…

Histology: This is what you're really made of. — Histology Look-a-like Adult T-cell leukemia.

Function of the lymph nodes (LN). LN are the site where immune reactions or suppression takes place. Cells of the afferent or efferent lymphatics are collected via LN dissection and the cells can be analysed. As well as different dendritic cell (DC) populations, different lymphocyte subpopulations such as CD4+ T cells or γδ T cells are also detected. Within the paracortex of the lymph node, DC present antigens to T cells which proliferate and differentiate into effector or helper T cells…

Lymph nodes (LN) are one of the important sites in the body where immune responses to pathogenic antigens are initiated. This immunological function induced by cells within the LN is an extensive area.

This human T cell (in blue) is under attack by HIV (in yellow), the virus that causes AIDS. The virus specifically targets T cells, which play a critical role in the body’s immune response against invaders like bacteria and viruses. eth Pincus, Elizabeth Fischer and Austin Athman, National Institute of Allergy and Infectious Diseases, National Institutes of Health

Lymph containing lymphocytes, antigen, and soluble mediators drains from surrounding tissues and enters the lymph nodes via afferent lymphatic vessels. The lymph node consists of a cortex and a medulla. The outermost area of the cortex has B cells organized into lymphoid follicles, and its deep, or paracortical, area consists mainly of T cells and dendritic cells. After B cells encounter antigens for which they have receptors, along with the appropriate T cells, central areas of marked B…
