CD30 antigen, also known as TNFRSF8, is a trans-membrane glycoprotein of the tumor necrosis factor receptor (TNFR) superfamily. Normally CD30 is restricted to activated B and T lymphocytes while rarely expressed by resting counterparts. CD30 has pleiotropic effects on the growth and survival of cells involving NF-κB signaling pathway. It is associated with almost all Hodgkin lymphoma (HL) and some subtypes of non-Hodgkin lymphoma (NHL) such as anaplastic large cell lymphoma (ALCL) at diagnosis as well as relapse. Therefore, CD30 is a very attractive target for the immunotherapy of these diseases. Brentuximab vedotin (Adcetris, Seattle Genetics), approved by FDA in 2011 for relapsed or refractory HL and systemic ALCL, is an antibody-drug conjugate (ADC) directed to CD30. Anti-CD30 CAR-T cell therapies are also being developed in many institutes and companies.
The Immune System, Inflammation, and Cancer
Anti-CD30 CAR-T Cell Therapy
Several clinical trials have been initiated for anti-CD30 CAR-T therapy. Patients with relapsed or refractory CD30+ HL or NHL are recruited. In a Phase I trial, nine patients were treated with autologous anti-CD30 CAR EBV-specific cytotoxic T-lymphocytes (CTLs). The CTLs were involved due to their long persistence in the blood stream for many years, potentially induces a prolonged anti-tumor effect. The anti-CD30 CAR-CTLs produced no adverse events, however, only two patients had a complete or partial response. Meanwhile, a novel 4th generation anti-CD30 CAR incorporated with an inducible caspase 9 suicide gene is being evaluated for both efficacy and safety.
Animal Models for in vivo Study of anti-CD30 CAR-T Cell Therapy
We have developed multiple animal models for the preclinical in vivo assay of anti-30 CAR-T cells. Several kinds of CD30+ cell lines or human primary HL and NHL cells, and some CD30 transfected cell lines are injected subcutaneously, intraperitoneally, or intravenously in SCID mice to create tumors in the mice. We also provide rats and non-human primates (NHPs) models to meet your special requirements.
