Cancer ang chi natna khirh tak takte enkawlna thar, hmasawn tak tak a awm tih i hre tawh mai thei. A chang chuan doctor chuan, "Hei atan hian damdawi bik a awm a, chu chuan kan taksa hriselna (immune system) a hmang a ni," a ti mai thei bawk. Vawiin hian damdawi lama hmasawnna lian tak nei thei enkawlna chungchang kan sawi dawn a ni. Chungte chu monoclonal antibodies an ti a. A hming hi a buaithlak deuh a, mahse a thawnthu erawh a awlsam hle. Hei hi eng nge a nih i en ang u.
Heng monoclonal antibodies te hi engte nge ni?
A awlsam zawngin, hengte hi lab-a siam protein bik an ni a, kan taksain a pianphung atanga a siam antibodies ang bawkin hna a thawk a ni.
Tunah chuan han ngaihtuah teh, kan taksa hi ram ang mai a ni. He ram humhalh tur hian sipai a awm a. Chu sipai chu kan immune system a ni . Pawn lam atanga lo chhuak hrik leh natna thlentu thil (heng antigens kan ti thin) te hi kan rama hmelma lo kal ang mai an ni. Heng antibody te hi kan sipaiah hian sipai bik an ni. An hna chu heng hmelma te hi zawn chhuah, man leh tihboral hi a ni.
A châng chuan kan taksaah cancer cell ang chi thil hi lo thang lian mah se, kan taksa hriselna (immune system) hian a hre thei lo. Chu chu pawn lam atanga tanpuina kan zawn lai a ni.
Monoclonal antibodies hi, a awlsam zawnga sawi chuan, lab-a siam, specially trained, super-smart, cloned sipai ang mai a ni. "Mono" tih awmzia chu "pakhat" tihna a ni. "Clonal" tih awmzia chu "copy" tihna a ni. Chu chu super-smart antibody pakhat thlan chhuah a ni a, a copy dik tak maktaduai tam tak chu lab-ah siam a ni tihna a ni. He antibodies sipai rual hi damdawi atan kan taksaah an inject leh thin. Natna thlentu cell (e.g., cancer cell)-ah an kal nghal a, an inzawm a, kan taksa hriselna (immune system) ngei pawhin a tihchhiat theih nan an pui bawk.
Hetiang damdawi chi hming i pek hi a tawpah "mab" tih ziak pathum (e.g. Trastuzumab, Rituximab) a awm chuan Monoclonal Antibody a ni tihna a ni.
Monoclonal leh polyclonal hi eng nge an danglamna?
Hei pawh hi a awlsam hle.
- Monoclonal: Hei hi sniper ang mai a ni. Target pakhat chauh a awm. Heng antibodies te hi antigen pakhat chauh nena inzawm tura siam an ni . Chuvangin an specific hle a, target an pelh lo ang.
- Polyclonal: "Poly" tih awmzia chu "tam tak" tihna a ni. Hengte hi antibody hrang hrang inzawmkhawm a ni. Hriamhrei hrang hrang nei sipai ang bawkin antigen chi hrang hrang an bei thei a ni .
Monoclonal antibodies hi enkawlna atan hman a ni ber a, a chhan chu a bik taka target a nih vang a ni.
Hengte hi eng atan nge an hman?
He inenkawl dan hi tunah chuan thil tam takah hman a ni ta. Research atanga natna tihdam thlengin an hmang nasa hle.
