| lymphoidocyte | A primitive mesenchymal cell believed to be capable of differentiating into all types of lymphoid cells, including lymphocytes, littoral cells, and reticular cells of lymph nodes. (05 Mar 2000) |
|---|---|
| lymphokine | <growth factor> Substance produced by a leucocyte that acts upon another cell. Examples are interleukins, interferon alpha, lymphotoxin (tumour necrosis factor alpha), granulocyte monocyte colony-stimulating factor (GM-CSF). The term is becoming less common and cytokine, a more general term, is taking over. Cytokines include lymphokines. (20 Mar 1998) |
| lymphokines | Soluble protein factors generated by activated lymphocytes that affect other cells, primarily those involved in cellular immunity. (12 Dec 1998) |
| lymphokinesis | 1. Circulation of lymph in the lymphatic vessels and through the lymph nodes. 2. Movement of endolymph in the saemicircular canals of the inner ear. Synonym: lymphocinesis, lymphocinesia. Origin: Lympho-+ G. Kinesis, movement (05 Mar 2000) |
| lympholeukocyte | <haematology> White cell of the blood that are derived from stem cells of the lymphoid series. Two main classes are recognised, T and B lymphocytes, the latter responsible (when activated) for production of antibody, the former subdivided into subsets (helper, suppressor, cytotoxic T-cells) and responsible both for cell-mediated immunity and for stimulating B-cells. (18 Nov 1997) |
| lymphology | Synonym: lymphangiology. Origin: Lympho-+ G. Logos, study (05 Mar 2000) |
| lymphoma | <oncology, tumour> Malignant tumour of lymphoblasts derived from B lymphocytes. most commonly affects children in tropical Africa: both Epstein Barr virus and immunosuppression due to malarial infection are involved. (18 Nov 1997) |
| lymphoma, aids-related | B-cell lymphoid tumours that occur in association with aids. Patients often present with an advanced stage of disease and highly malignant subtypes including burkitt lymphoma, immunoblastic large-cell lymphoma, small non-cleaved-cell lymphoma and diffuse large-cell lymphoma. The tumours are often disseminated in unusual extranodal sites and chromosomal abnormalities are frequently present. It is likely that polyclonal B-cell lymphoproliferation in aids is a complex result of ebv infection, HIV antigenic stimulation, and T-cell-dependent HIV activation. (12 Dec 1998) |
| lymphoma, B-cell | A group of heterogeneous lymphoid tumours generally expressing one or more B-cell antigens or representing malignant transformations of B-lymphocytes. (12 Dec 1998) |
| lymphoma, diffuse | Malignant lymphoma in which neoplastic cells diffusely infiltrate the entire lymph node without any definite organised pattern. Patients whose lymphomas present a diffuse pattern generally have a more unfavorable survival outlook than those presenting with a follicular or nodular pattern. (12 Dec 1998) |
| lymphoma, follicular | Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the lymph nodes. The nodules resemble to some extent the germinal centres of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular centre B-lymphocytes. This class of lymphoma usually occurs in older persons, is commonly multinodal, and possibly extranodal. Patients whose lymphomas present a follicular or nodular pattern generally have a more indolent course than those presenting with a diffuse pattern. (12 Dec 1998) |
| lymphoma, high-grade | One of the three major prognostic groupings for non-hodgkin lymphomas as proposed in the working formulation of the non-hodgkin's lymphoma pathologic classification project sponsored by the national cancer institute (1981). Lymphomas falling within this group have a relatively unfavorable survival potential. (12 Dec 1998) |
| lymphoma, intermediate-grade | One of the three major prognostic groupings for non-hodgkin lymphomas as proposed in the working formulation of the non-hodgkin's lymphoma pathologic classification project sponsored by the national cancer institute (1981). Lymphomas falling within this group have an intermediate survival potential. (12 Dec 1998) |
| lymphoma, large-cell | A form of malignant lymphoma in which the malignant cells resemble histiocytes morphologically but are presently considered to be derived from lymphoid elements. These cells are irregular in shape with relatively abundant, frequently acidophilic cytoplasm. Large-cell lymphoma can occur in both nodular (follicular) and diffuse forms, with the latter being more frequently seen. (12 Dec 1998) |
| lymphoma, large-cell, diffuse | Malignant lymphoma composed of large cells which may be both cleaved and noncleaved. The pattern is predominantly diffuse. most of these lymphomas represent the malignant counterpart of B-lymphocytes at midstage in the process of differentiation. (12 Dec 1998) |
