T-cell clonality assays: how do they compare?


Cozzio, A; French, L E (2008). T-cell clonality assays: how do they compare? Journal of Investigative Dermatology, 128(4):771-773.

Abstract

The distinction between certain benign cutaneous lymphocytic infiltrates and cutaneous T-cell lymphoma (CTCL) can be a challenging problem in clinical practice. An imperfect but useful tool in this circumstance is the analysis of T-cell clonality or monoclonality by assessing T-cell receptor (TCR) gene rearrangements. "Monoclonality" describes the origin of a specific human malignant tumor from one single cell from which the entire tumor is derived. The term is used to describe the early steps in tumorigenesis; in later stages of tumor growth and progression, monoclonal tumor cells may acquire a mutator phenotype, rendering the genome unstable. The resulting genetic heterogeneity may ultimately lead to subclones in the formerly monoclonal population of tumor cells.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
