If the lymph node or similar tissue is reactive, or otherwise benign, it should possess a mixture of kappa positive and lambda positive cells. If, however, one type of light chain is significantly more common than the other, the cells are likely all derived from a small clonal population, which may indicate a malignant condition, such as B-cell ...
The Lambda2 method, or Lambda2 vortex criterion, is a vortex core line detection algorithm that can adequately identify vortices from a three-dimensional fluid velocity field. [1] The Lambda2 method is Galilean invariant , which means it produces the same results when a uniform velocity field is added to the existing velocity field or when the ...
This cytokine is expressed in B cell lineage cells, and acts as a potent B cell activator. It has been also shown to play an important role in the proliferation and differentiation of B cells. [7] BAFF is a 285-amino acid long peptide glycoprotein which undergoes glycosylation at residue 124.

Cellular immunity protects the body through: T-cell mediated immunity or T-cell immunity: activating antigen-specific cytotoxic T cells that are able to induce apoptosis in body cells displaying epitopes of foreign antigen on their surface, such as virus-infected cells, cells with intracellular bacteria, and cancer cells displaying tumor antigens;
It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. [5] When CD27 binds CD70, a signaling cascade leads to the differentiation and clonal expansion of T cells. [11] The cascade also results in improved survival and memory of cytotoxic T cells and increased production of certain cytokines. [12]
Defects in the CD43 molecule are associated with the development of Wiskott–Aldrich syndrome. [8] It also appears in about 25% of intestinal MALTomas. [citation needed] Using immunohistochemistry, CD43 can be demonstrated in the paracortical T-cells of healthy lymph nodes and tonsils; it is also positive in a range of lymphoid and myeloid tumours.
Antitermination in lambda is induced by two quite distinct mechanisms. The first is the result of interaction between lambda N protein and its targets in the early phage transcripts, and the second is the result of an interaction between the lambda Q protein and its target in the late phage promoter.
