abstract = {The low dose application of chemotherapeutic agents such as
paclitaxel was previously shown to initiate anti-tumor
activity by neutralizing myeloid-derived suppressor cells
(MDSCs) in melanoma mouse models. Here, we investigated
immunomodulating effects of low-dose paclitaxel in 9
metastatic melanoma patients resistant to prior treatments.
Three patients showed response to therapy (two partial
responses and one stable disease). In responding patients,
paclitaxel decreased the frequency and immunosuppressive
pattern of MDSCs in the peripheral blood and skin
metastases. Furthermore, paclitaxel modulated levels of
inflammatory mediators in the serum. In addition, responders
displayed enhanced frequencies of tumor-infiltrating CD8+ T
cells and their activity indicated by the upregulation of
CD25 and TCR ζ-chain expression. Our study suggests that
low-dose paclitaxel treatment could improve clinical outcome
of some advanced melanoma patients by enhancing anti-tumor
immunity and might be proposed for combined melanoma
immunotherapy.},
