PDGFRA and mature T-cell and NK-cell non-Hodgkin lymphoma: In this manuscript, the authors reported that AILT and other PTCL have rather similar GEP, possibly sharing common oncogenic pathways. In addition, they found that the molecular signature of follicular T helper cells was significantly overexpressed in AILT. Finally, several genes, such as PDGFRA and VEGF, which are deregulated in AILT and represent potential therapeutic targets, were identified.
