Kwiminyaka yakutshanje, ukuphuhliswa kwezitofu ze-DNA kubonise isithembiso esibalulekileyo kwintsimi yokugonywa. Ezi zitofu zisebenza ngo
ukwazisa iqhekezana le-DNA (i-plasmid) elincinci, elijikelezayo elifaka i-protein ye-antigenic ye-pathogen, ikhuthaza amajoni omzimba ukuba aqaphele kwaye alwe i-pathogen yokwenyani ukuba ifunyenwe. Nangona kunjalo, indlela yokuhanjiswa kwezi zitofu zeDNA idlala indima ebalulekileyo ekusebenzeni kwazo. Iinaliti ezisekelwe kwiinaliti eziqhelekileyo, ngelixa zisebenza, ziza kunye neengxaki ezahlukeneyo ezifana ne-aspain, ukulimala kwenaliti, kunye ne-needle phobia. Oku kukhokelele ekwandeni komdla kwezinye iindlela zonikezelo, enye yazo sisitofu esingenanaliti.
Yintoni Izitofu ezingaNaliti?
Izitofu ezingenanaliti zizixhobo ezenzelwe ukuhambisa amayeza okanye ugonyo ngaphandle kokusetyenziswa kwenaliti yesintu. Basebenza ngokusebenzisa ijethi yoxinzelelo oluphezulu ukungena esikhumbeni kwaye bahambiseinto ngqo kwithishu. Le teknoloji iye yabamalunga namashumi eminyaka kodwa isandula ukufumana ingqalelo engakumbi ngenxa yenkqubela phambili kuyilo kunye nokusebenza kwayo.
Izinto eziluncedo kwiinaliti ezingenazinaliti
Ukuhanjiswa okungenabuhlungu: Enye yezona zinto ziluncedo kakhuluii-injection ezingenanaliti kukunciphisa intlungu kunye nokungonwabi. Ukungabikho kwenaliti
kuphelisa iintlungu ezibukhali ezinxulumene nezitofu zendabuko, okwenza amava abe mnandi ngakumbi kwizigulane.
Ukupheliswa kweeMingcipheko eziNxulumene neNaliti: Ii-injection ezingenaliti zisusa umngcipheko wokulimala kwenaliti, eyona ndawo ixhalabileyo kwimimiselo yezempilo. Oku akukhuseli kuphela abasebenzi bezempilo kodwa kunciphisa umngcipheko wosulelo kunye nosulelo.
UkuFumana koGonyo oloNgezelelweyo: I-needle phobia sisizathu esiqhelekileyo sokuthingaza kwesitofu sokugonya. Ngokususa inaliti, ezi zixhobo zinokunyusa ukwamkelwa nokwamkelwa kwesitofu sokugonya, nto leyo ebalulekileyo kumanyathelo empilo yoluntu.
Ukuphuculwa koKhuseleko lwe-Immunogenicity: Olunye uphononongo lucebise ukuba ii-injection ezingenanaliti zinokuphucula ukugonywa kwezitofu zokugonya. Ijethi yoxinzelelo oluphezulu inokunceda ekusasazekeni ngcono kwesitofu sokugonya ngaphakathi kwethishu, ekhokelela kwimpendulo eyomeleleyo yokhuselo lomzimba.
Ukusebenza kwezitofu ezingaNaliti ze-DNA
Ukusebenza kwezitofu ezingenanaliti ekuhambiseni izitofu zokugonya ze-DNA yindawo yophando olusebenzayo. Izifundo ezininzi zibonise iziphumo ezithembisayo:
UkuFumana kwe-DNA eyongeziweyo: Indlela yokuhanjiswa koxinzelelo oluphezulu lwee-injection ezingenanaliti iququzelela ukufunyanwa okungcono kwe-plasmids ye-DNA ngeeseli. Oku kubalulekile kugonyo lwe-DNA njengoko iplasmid idinga ukungena kwiiseli ukuvelisa iprotein ye-antigenic.
Ukusabela okunamandla kuMzimba: Uphando lubonise ukuba izitofu zokugonya ze-DNA ezihanjiswa ngeenaliti ezingenazinaliti zinokwenza ugonyo olunamandla nangaphezulu.
impendulo ezinzileyo yamajoni omzimba xa kuthelekiswa neendlela zemveli ezisekwe kwiinaliti. Oku kubalelwa kunikezelo olusebenzayo kunye nokusasazwa ngcono kwesitofu sokugonya ngaphakathi kwithishu.
Ukhuseleko kunye nokunyamezela: Izitofu ezingenanaliti zifunyenwe zikhuselekile kwaye zinyamezelwa kakuhle zizigulane. Ukungabikho kweenaliti kunciphisa umngcipheko wokuphendula okungalunganga kwindawo yokutofa, njenge-aspain, ukuvuvukala, kunye nokubomvu.
Imingeni kunye neNgqwalasela
Ngelixa ii-injection ezingenanaliti zibonelela ngeenzuzo ezininzi, kusekho imingeni kunye neengqwalasela ekufuneka ziqwalaselwe:
Ixabiso: Izixhobo zokutofa ezingenanaliti zinokubiza ngaphezulu kunesirinji zesintu, ezinokunqanda ukwamkelwa kwazo okuxhaphakileyo, ngakumbi kwiindawo ezinobuncwane obuphantsi.
Uqeqesho: Uqeqesho olululo luyafuneka kubaboneleli bezempilo ukuba basebenzise izitofu ezingenanaliti ngokufanelekileyo. Ukusetyenziswa gwenxa kunokukhokelela ekunikezelweni ngokungafanelekanga kwesitofu sokugonya kunye nokuncipha kokusebenza kakuhle.
Ukugcinwa kwesixhobo: Ezi zixhobo zifuna ukugcinwa rhoqo kunye nokulinganisa ukuqinisekisa ukusebenza okufanayo. Oku kunokuba ngumceli mngeni wolungiselelo kwezinye iindawo zokhathalelo lwempilo.
Ukuqukumbela
Izitofu ezingenanaliti zimela ukuqhubela phambili okuthembisayo ekuhanjisweni kwezitofu zokugonya ze-DNA. Ukukwazi kwabo ukubonelela ngokungenabuhlungu, okukhuselekileyo, kunyeugonyo olunokuba luncedo ngakumbi lwenza ukuba umntu abe nomtsalane kunezinye iindlela zemveli ezisekwe kwiinaliti. Nangona kukho imingeni ekufuneka yoyiswe, uphuhliso oluqhubekayo kunye nokuphuculwa kobu buchwepheshe kunokudlala indima ebalulekileyo ekuphuculeni ukuhanjiswa kwesitofu sokugonya kunye neziphumo zempilo yoluntu. Njengoko uphando luqhubela phambili, ii-injection ezingenanaliti zinokuba sisixhobo esiqhelekileyo kumlo ochasene nezifo ezosulelayo, ukubonelela ngamava okugonya okukhululekile kunye nokusebenza kakuhle kubo bonke.
