L-591 Cells

The L-591 cell line is one of several neoplastic cell lines derived from patients with Hodgkin's disease, specifically of the nodular sclerosing subtype. It was established as part of a group of Hodgkin's lymphoma cell lines, including L-428 and L-540, and has been instrumental in advancing the understanding of this hematologic malignancy. L-591 cells are characterized by aneuploidy and exhibit various structural and numerical chromosomal abnormalities, which are indicative of their neoplastic origin. The line is particularly valuable in research due to its distinct chromosomal patterns and its ability to proliferate in vitro, making it a reliable model for studying the cellular mechanisms of Hodgkin's lymphoma. One of the defining features of L-591 cells is their immunophenotype. The cells express Ia-like antigens and receptors associated with T cells but lack markers typical of other hematopoietic lineages, such as myeloid cells, monocytes, and macrophages. Notably, L-591 cells do not produce surface or cytoplasmic immunoglobulins, nor do they exhibit Epstein-Barr Virus (EBV)-specific antigens, such as EBNA. This absence of immunoglobulins and EBV antigens distinguishes L-591 from other EBV-positive Hodgkin's lymphoma cell lines and highlights its utility in exploring the specificities of Hodgkin's lymphoma pathology that are independent of EBV infection. The L-591 cell line is morphologically similar to the Reed-Sternberg (RS) and Hodgkin (H) cells that are characteristic of Hodgkin's lymphoma. These cells play a crucial role in the research of Hodgkin's disease, serving as a model for understanding the pathogenesis of the disease and for identifying potential therapeutic targets. The unique features of L-591, combined with its established use in laboratory settings, make it an essential tool in the study of Hodgkin's lymphoma, contributing significantly to the body of knowledge surrounding this complex malignancy.
