Marianna Dobi, Ágnes Szilágyi, Dorottya Csuka, Lilian Varga, Zoltán Prohászka, Csaba Bereczki, Gábor Kovács, Ferenc Fekete,

The complement system is essential for protection against infections in oncologic patients because of the chemotherapy-induced immunosuppression. One of the key elements in the activation of the complement system via the lectin pathway is the appropriate functioning of mannose-binding lectin (MBL) and mannose-binding lectin-associated serine protease 2 (MASP2) complex. The ... Read more >>
