Marsdenia tenacissima, a traditional Chinese medicine, is long been used to treat various diseases including asthma, cancer, trachitis, tonsillitis, pharyngitis, cystitis, and pneumonia. Although Marsdenia tenacissima has been demonstrated to have strong anti-tumor effects against primary tumors, its effect on cancer metastasis remains to be defined, and the molecular mechanism underlying the anti-metastatic effect is unknown. In the present study, we investigated the effects of XAP (an extract of Marsdenia tenacissima) on A549 lung cancer cell migration and explored the role of CCR5-CCL5 axis in the anti-metastatic effects of XAP. Our resutls showed that XAP inhibited A549 lung cancer cell migration and invasion in a dose-dependent manner. The protein levels of CCR5, but not CCR9 and CXCR4, were decreased by XAP. The secretion of CCL5, the ligand of CCR5, was reduced by XAP. XAP down-regulated Rho C expression and FAK phosphorylation. In conclusion, XAP inhibited A549 cell migration and invasion through down-regulation of CCR5-CCL5 axis, Rho C, and FAK.

Primary immunodeficiencies with selective susceptibility to EBV infection are rare conditions associated with severe lymphoproliferation. We followed a patient, son of consanguineous parents, referred to our center for recurrent periodic episodes of fever associated with tonsillitis and adenitis started after an infectious mononucleosis and responsive to oral steroid. An initial diagnosis of periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis syndrome was done. In the following months, recurrent respiratory infections and episodes of keratitis were also observed, together with a progressive reduction of immunoglobulin levels and an increase of CD20+ cells. Cell sorting and EBV PCR showed 25,000 copies for 100,000 leukocytes with predominant infection of B lymphocytes. Lymph node's biopsy revealed reactive lymphadenopathy with paracortical involvement consistent with a chronic EBV infection. Molecular analysis of XIAP, SHA2D1A, ITK, and CD27 genes did not detect any pathogenic mutation. The patients underwent repeated courses of anti-CD20 therapy with only a partial control of the disease, followed by stem cell transplantation with a complete normalization of clinical and immunological features. Whole exome sequencing of the trio was performed. Among the variants identified, a novel loss of function homozygous c.163-2A>G mutation of the CD70 gene, affecting the exon 2 AG-acceptor splice site, fit the expected recessive model of inheritance. Indeed, deficiency of both CD27, and, more recently, of its ligand CD70, has been reported as a cause of EBV-driven lymphoproliferation and hypogammaglobulinemia. Cell surface analysis of patient-derived PHA-T cell blasts and EBV-transformed lymphoblastoid cell lines confirmed absence of CD70 expression. In conclusion, we describe a case of severe chronic EBV infection caused by a novel mutation of CD70 presenting with recurrent periodic fever.
