Kan taksa hi zirtirna bu lian tak angin i ngaihtuah thei ang. He thupek bu-a thupek te te hi "genes" kan ti a ni. Heng genes te hian kan taksa chhunga thil awm zawng zawng, entirnan, kan mit rawng, kan sam texture te hi a hril vek a ni. Chuvangin, a chang chuan he thupek bu-a thupek pakhata tihsual tlemte, chu chu lehkha thlak danglam a nih chuan natna khirh tak a thlen thei tihna a ni. Vawiin hian chutiang thupek dik lo siamthatna tur, emaw, thupek dik thar dahna tur damdawi hmanraw changkang tak tak kan sawi dawn a ni. Hei hi gene therapy an ti a.
Gene therapy chu eng nge ni mai?
A awlsam zawngin sawi ila, gene therapy hi genetic disorder enkawlna atana hmanraw bik a ni. Kan taksa genes hian protein siam dan tur thupek a pe a. Gene a inthlak emaw, a chhiat emaw chuan a protein siam chu siam dik lo emaw, tihtawp vek emaw theih a ni. Hei hi genetic disorder siamtu a ni.
Gene therapy hian natna thlentu gene dik lo chu a thlak danglam emaw , i cell te chu gene working copy thar a pe emaw a ni . Hei hi vawi khat enkawlna a ni fo thin. Hetianga enkawl hnu hian i taksain a mamawh proteins dik takin a siam thei a, chu chuan symptoms a ti reh thei a ni.
Engtin nge he enkawlna hian hna a thawh?
Gene therapy hnathawh dan tlangpui pathum a awm a. Hei hi chiang taka hrethiam turin a hnuaia table hi han en ila.
| Enkawl dan tur | A awlsam zawngin... | Engnge i tih? |
|---|---|---|
| Gene Addition tih a ni | Gene tha thar dah luh. | Gene bik a chhiatna avanga taksaah protein mamawh a siam chhuah loh chuan chu protein siam thei gene hrisel copy chu cell-ah dah a ni. |
| Gene Editing a ni | Gene dik lo siamthat. | Scientist te chuan CRISPR/cas9 ang chi hmanraw bik hmangin natna thlentu gene dik lo chu "cut and paste" an ti thin. Tichuan, chu gene chuan protein dik tak chu a siam tan ta a ni. |
| Gene Silencing tih a ni | Gene dik lo off tir. | Gene thenkhat chuan hna an thawk dik lo a, taksa tana tha lo protein an siam thin. Hetiang hmanrua hian chutiang thupek dik lo pe thin gene hnathawh chu a titawp a ni. Chu chu a ti ngawih ngawih tihna a ni. |
Engtin nge heng modified genes te hi taksaah hian i dah lut thin?
Okay, tunah chuan zawhna i nei ta: Engtin nge heng modified genes te hi taksaah i luh tir? Scientist-te chuan heng genes te hi parcel ang chi thilah an dah khawm thin. He parcel hi "vector" an ti a. He vector hi a bik taka siam danglam virus a ni fo thin.
Lungngai suh! Hei hi virus min ti na lo. Min natna siam theihna chu a tibo vek a, chu ai chuan kan gene hrisel tak takte nen a rawn dah lut ta zawk a ni. Delivery vehicle ang maiin he carrier hna awmchhun chu genes phurh a, cell dik tak hnena thlen hi a ni.
Treatment thenkhatah chuan nangmah ngeiin thisen stem cell thenkhat lak a, lab-ah siam danglam a, chu chu i taksaah dah leh a ni. A dang erawh chuan heng genes awmna carrier hi injection angin emaw, vein chhunga infusion angin emaw pek a ni. Hun a kal zel a, heng gene thar nei cell te hi an inthen darh a, an lo pung a, natna vei cell te chu an thlak ta a ni. Chuvangin he enkawlna hian nghawng a neih hi rei tak daih tur a ni.
Gene therapy hmang hian eng natna nge tihdam theih?
Gene therapy hi gene defect pakhat avanga natna awmte tan a hlawhtling ber a ni. Tuna he enkawlna hi phalna pek a nihna natna thenkhat chu hetiang hi a ni:
- Thluak tibuaitu genetic natna, Cerebral Adrenoleukodystrophy .
- Thisen natna rochun: Entîr nân , sickle cell natna, thalassemia, leh hemophilia .
- Neuromuscular natna rochun: Duchenne Muscular Dystrophy leh Spinal Muscular Atrophy ang chi natna.
- Mit natna rochun: Mit hmuhna tichhe thei natna, Leber’s Congenital Amaurosis ang chi te.
- Genetic natna dang Metachromatic Leukodystrophy te pawh a awm thei.
Hei bakah hian cancer leh HIVScientist-te chuan gene therapy hi natna hrang hrang,...
Gene therapy hian eng nge a thatna leh a that lohna?
Damdawi dang ang bawkin gene therapy hian a hlawkna bakah a hlauhawmna leh a that lohna thenkhat a nei bawk. Hengte hi fimkhur a pawimawh hle.
| Pros | Cons leh Limitations te |
|---|---|
| Beiseina Thar: Natna tam tak enkawlna kawng dang a tlakchhamna enkawlna kawng thar a pe. | Hman harsa: Technology man to tak leh a tlem avangin mi zawng zawngin he enkawlna hi an hmu thei lo. |
| A awlsamna: Gene therapies tam zawk hi chu dam chhunga vawi khat chauh tih theih a ni. Nitin damdawi ei a ngai lo. | Side effects: Enkawlna zawng zawng ang bawkin side effects awm theihna a awm. Entirnan, taksa immune system hian gene carrier (virus) chu a reacted thei a ni. |
| Enkawlna hmasa: Natnain taksa a tihchhiat nasa hmaa he enkawlna hi hmuh theih a nih chuan chu chhiatna chu ven theih a ni. | Inbuatsaihna kalphung: Gene therapies thenkhatah chuan enkawl hmain enkawlna dang, chemotherapy ang chi te a ngai a, chu chuan side effect duhawm lo tak a thlen thei a ni. |
| Natna bulpui enkawl dan: A natna lan chhuah dan chauh enkawl ai chuan a chhan bulpui ber, chu chu a genetic defect ngei hi kan enkawl a ni. | Field thar a la ni reng: Hei hi kum sawm tam tak chhung chu zirchianna stage-ah awm tawh mah se, damdawi lama a hmanna chu a la thar hle. Zir tur tam tak a la awm. |
Gene therapy hian genetic disease nei tan chuan thutiam ropui tak a nei a ni. Natna pakhat bulpui ber a tidam thei a, a lan chhuah dan chauh ni lovin. Hei hi field thar chhuak ni mahse, tun hmaa enkawlna kawng tlemte nei tawh damlote tan nun tidanglam thei result a pe thei a ni. Nangmah emaw, i chhungte zinga tu emaw hian genetic disease i neih chuan hemi chungchang hi i doctor nen inbia a , hriat belh a tha ber.
Take-Home Thuchah a ni
- Gene therapy hi enkawlna kawng hmasawn tak a ni a, chu chuan genetic natna thenkhat thlentu genetic defect hnuaia awm chu a siam tha a ni.
- Hei hian gene dik lo a siam\hat emaw, taksaah gene hrisel copy a dah emaw a ni.
- Hei hi vawi khat enkawlna ni fo mah se, tun dinhmunah chuan khawvel hmun tinah a awm lo va, a man pawh a to hle.
- Enkawlna dang ang bawkin a thatna te, a hlauhawmna te leh a side effect te a awm a.
- Chutiang enkawlna chungchanga thutlukna i siam hmain i doctor nen he thu hi sawiho hmasak a pawimawh fo thin.
