Miyagaki found that CCR3 was associated with anaplastic large cell lymphoma (ALCL) cells via ERK1/2 activation [16]; CCR3 played a role in the recruitment and retention of CD30+ malignant T cells to the skin in skin-specific cutaneous T-cell lymphoma (CTCL) [17]. Here, MAPK3 is linked to anaplastic large cell lymphoma.
