Study summary Full title Melanoma-derived small extracellular vesicles induce lymphangiogenesis and metastasis through a NGFR-dependent mechanism All authors Susana García-Silva, Alberto Benito-Martín, Laura Nogués, Alberto Hernández-Barranco, Marina S.

Cancer Abstract Secreted extracellular vesicles (EVs) influence the tumor microenvironment and promote distal metast (show more...)Secreted extracellular vesicles (EVs) influence the tumor microenvironment and promote distal metastasis. Here, we have analyzed the involvement of melanoma-secreted EVs in lymph node pre-metastatic niche formation in murine models. We found that small EVs (sEVs) derived from metastatic melanoma cell lines spread through the lymphatic system and were taken up by lymphatic endothelial cells, reinforcing lymph node metastasis. Remarkably, sEVs enhanced lymphangiogenesis and tumor cell adhesion by inducing ERK, NF-kB activation and ICAM-1 expression in lymphatic endothelial cells. Importantly, ablation or inhibition of NGFR/p75NTR in sEVs reversed the lymphangiogenic phenotype, decreased lymph node metastasis and extended survival in pre-clinical models. Furthermore, NGFR expression was augmented in human lymph node metastases relative to matched primary tumors and frequency of NGFR+ metastatic melanoma cells in lymph node correlated with patient survival. In summary, we found that NGFR is secreted in melanoma-derived sEVs reinforcing lymph node pre-metastatic niche formation and metastasis.

Remarkably, sEVs enhanced lymphangiogenesis and tumor cell adhesion by inducing ERK, NF-kB activation and ICAM-1 expression in lymphatic endothelial cells. Importantly, ablation or inhibition of NGFR/p75NTR in sEVs reversed the lymphangiogenic phenotype, decreased lymph node metastasis and extended survival in pre-clinical models. Furthermore, NGFR expression was augmented in human lymph node metastases relative to matched primary tumors and frequency of NGFR+ metastatic melanoma cells in lymph node correlated with patient survival. In summary, we found that NGFR is secreted in melanoma-derived sEVs reinforcing lymph node pre-metastatic niche formation and metastasis.
