CD40
CD40 (kluster diferensiasi 40) adalah protein yang dapat ditemui pada sel penyaji antigen, dan protein ini dibutuhkan untuk mengaktivasi sel tersebut. Reseptor protein yang disandikan oleh gen ini merupakan bagian dari superfamili reseptor TNF. Reseptor ini penting dalam menengahi berbagai macam respons imun, termasuk pembentukan pusat germinal.[1]
CD40 diketahui dapat berinteraksi dengan TRAF2,[2][3][4] TRAF3,[3][5][6][7] TRAF6,[3][7] TRAF5[3][8] dan TTRAP.[9]
Molekul CD40 merupakan target potensial untuk imunoterapi kanker. Terdapat sejumlah uji coba klinis yang sedang berlangsung dan juga yang telah dituntaskan dengan antibodi monoklonal anti-CD40 yang dipakai untuk mengaktivasi respons sel T anti-tumor lewat aktivasi sel-sel dendritik.[10]
