Besides being a potent stimulator of angiogenesis, VEGF-A also has the capacity to enhance the expression of TSLP in keratinocytes and, accordingly, the serum concentrations of VEGF-A correlate with the lesional expression of TSLP in erythrodermic CTCL patients (Sakamoto et al., 2018). The gene discussed is TSLP; the disease is primary cutaneous T-cell non-Hodgkin lymphoma.
