Lenalidomide and Chronic Lymphocytic Leukemia

Lenalidomide interferes with tumor-promoting properties of nurse-like cells in chronic lymphocytic leukemia.

Lenalidomide is an immunomodulatory agent clinically active in chronic lymphocytic leukemia patients. The specific mechanism of action is still undefined, but includes modulation of the microenvironment. In chronic lymphocytic leukemia patients, nurse-like cells differentiate from CD14(+) mononuclear cells and protect chronic lymphocytic leukemia cells from apoptosis. Nurse-like cells resemble ...

Lenalidomide-induced upregulation of CD80 on tumor cells correlates with T-cell activation, the rapid onset of a cytokine release syndrome and leukemic cell clearance in chronic lymphocytic leukemia.

BACKGROUND In chronic lymphocytic leukemia lenalidomide causes striking immune activation, possibly leading to clearance of tumor cells. We conducted this study to investigate the mechanism of action of lenalidomide and the basis for its unique toxicities in chronic lymphocytic leukemia. DESIGN AND METHODS Patients with relapsed chronic lymphocytic leukemia were treated with lenalidomide 20 m...

Rapid resolution of Mycobacterium marinum chronic skin infection during lenalidomide therapy for chronic lymphocytic leukemia.

The immunomodulatory drug lenalidomide is currently being evaluated for its antineoplastic properties in treating hematologic malignancies. However, its potential role in augmenting immune reactions against opportunistic infections has not been explored. We report the rapid resolution of chronic Mycobacterium marinum infection in a patient following initiation of lenalidomide therapy for chroni...

Immune dysfunction in chronic lymphocytic leukemia T cells and lenalidomide as an immunomodulatory drug.

Effect of curcumin on growth inhibition and gene expression reduction in chronic lymphocytic leukemia cells (CLL-CII)

Introduction: Chronic lymphocytic leukemia (CLL) is the most frequent leukemia in adults living in Western countries. with a diverse clinical course that due to life expectancy less than two years between patients finding ,new therapeutic strategies is essential for it. Curcumin as the biologic active of turmeric, has many biological properties such as anti-inflammatory, anti-oxidant, anti-diab...

Chemotherapy-induced augmentation of T cells expressing inhibitory receptors is reversed by treatment with lenalidomide in chronic lymphocytic leukemia.
