METHODS OF REDUCING LARGE GRANULAR LYMPHOCYTE AND NATURAL KILLER CELL LEVELS

The present disclosure relates to methods of treating diseases or disorders associated with LGL and/or NK cells, methods of reducing or depleting LGL and/or NK cells, and methods of inducing ADCC activity using antibodies that bind to a cell surface protein on LGL and/or NK cells and comprise enhanced ADCC activity. The present invention also relates to a method of depleting or reducing the numbers of large granular lymphocytes and natural killer cells in a human subject upon administration of CD94 or CD57 or NKG2A binding molecule that consists of a part that specifically binds to the CD94 or CD57 or NKG2A receptors and an immunoglobulin Fc part. In a specific embodiment, a method of the invention depletes or reduces the number of large granular lymphocytes and natural killer cells in spleen, blood, bone marrow, joints, or other tissues.
