Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza: Ukubuka konke okuphelele 

Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza Igxile ekuletheni abenzeli bezokwelapha ikakhulukazi kumaseli womdlavuza, ukunciphisa ukulimala kwezicubu ezinempilo. Le ndlela isebenzisa amasu ahlukahlukene, kufaka phakathi ama-nanoparticles, ama-antibodies kanye nama-peptides angena kumaselula, ukuthuthukisa ukusebenza kwezidakamizwa futhi anciphise imiphumela emibi, enikeza ukwelashwa okunembile okunembile ngokwengeziwe.

-Zwayo Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza

Ukwelashwa komdlavuza sekuvele kakhulu, nge Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza evelayo njengecebo elithembisayo. Le ndlela ihlose ukuletha ukukhetha izidakamizwa kumaseli womdlavuza, yandisa imiphumela yokwelapha ngenkathi inciphisa ukulimala kwezicubu ezinempilo. Ngokungafani ne-Chemotherapy Chemotherapy evamile, eyisabalalisa izidakamizwa kuwo wonke umzimba, ukulethwa okuhlosiwe kusetshenziswa izindlela ezahlukahlukene kumaseli womdlavuza ngokuqondile.

Ngobani Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza Izindaba

Indabuko ye-chemotherapy ivame ukuphumela emiphumeleni emibi ebalulekile ngoba ithinta amaseli womabili noma anempilo. Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza Inikeza isixazululo ngokuletha izidakamizwa ngqo kwisiza se-tumor. Lokhu kunciphisa ubuthi onobuthi, kuthuthukisa ukusebenza kwezidakamizwa, futhi kungahle kuthuthukiswe impilo yeziguli.

Amasu we Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza

Amasu amaningana aqashiwe aqashwa ngaphakathi Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza, yileso naleso sinezinzuzo kanye nemikhawulo yayo.

Ama-Nanoparticles

Ama-nanoparticles anezinhlayiya ezincane (1-100 NM) yakhelwe ukunika amandla okuzama kanye nokuletha izidakamizwa kumaseli womdlavuza. Zingakwazi ukubhekelwa ukubhekisa ama-receptors athile kumaseli womdlavuza, njenge-egfr noma i-HER2. Ama-Liposomes, ama-nanoparticles e-polymeric, kanye nama-nanoparticles e-inorganic asetshenziswa kakhulu. Umphumela wokuvuselelwa okuthuthukile nokugcinwa kabusha (EPR) uvumela ama-nanoparticles aqongelele nje izicubu zomsuka ngenxa ye-vasculature evuzayo.

Isibonelo: I-Doxil, i-liposomal doxorubicin, isidakamizwa esitholakala kwezentengiselwano

Izimbotshana zezidakamizwa ze-antibody-Drug (ADCs)

I-ADCS iqukethe i-antibon ye-monoclonal exhumene nomuthi we-cytotoxic. I-antibody ibopha ngokuqondile kwithagethi ye-antigen kumaseli womdlavuza, okuholele ngaphakathi kwe-ADC kanye nokukhishwa okulandelayo kwesidakamizwa ngaphakathi esitokisini.

Isibonelo: I-Adcetris (Brentuximab Vedotin) ihlose i-CD30, amaprotheni atholakala kumaseli athile e-lymphoma, alethe umenzeli we-microtubule-ukuphazamisa.

Ama-peptides angena kumaselula (ama-CPP)

I-CPPS ilandela ukulandelana kwe-amino acid okwenza lula ukungena kwezidakamizwa noma ama-nanoparticles kumaseli. Zingafakwa kuma-ejenti wezokwelapha noma ama-nanoparticles ukuthuthukisa ukwenziwa kwawo kwamaselula.

I-receptor-mediated endocytosis

Leliqhinga lifaka ukuqondisisa ama-receptors avelele kumaseli womdlavuza. Ama-ligands noma ama-antibodies ahlanganisa kulezi receptors asetshenziselwa ukuletha izidakamizwa noma ama-nanoparticles nge-endocytosis.

Indima ye-Shandong Baafa Cancer Research Institute's Indima

Isikhungo Sokucwaninga Nge-Shandong Baafa Cancer Research sibambe iqhaza ekucwaningeni nasekuthuthukiseni inoveli Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza izinhlelo. Ucwaningo lwabo lugxile ezindleleni ezenzelwe wena ezibheka amaphrofayili wezakhi zofuzo ezihlukile kanye nama-molecular zeziguli ngazinye, okuhlose ukuthuthukisa imiphumela yokwelashwa futhi kunciphise imiphumela emibi.

Isikhungo Sokucwaninga Nge-Shandong Baafa Cancer Research sisebenza nezibhedlela ezinjengesibhedlela saseShandong Baafa (https://baofahospital.com) Ukuqhuba izivivinyo zokwelashwa kanye nokuhumusha okutholakele kocwaningo kuzinhlelo zokusebenza ezisebenzayo.

Izinzuzo ze Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza

Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza inikeza izinzuzo ezimbalwa ezibalulekile ngaphezulu kwe-chemotherapy evamile:

• Ubuthi obuncishisiwe: Ngokuqondisa amaseli omdlavuza ngokuqondile, ukuvezwa kwezicubu ezinempilo kuya ezingutsheni ezinobuthi kuncishisiwe, kuholele emiphumeleni emibi embalwa.
• Impumelelo ethuthukisiwe: Ukugxila okuphezulu kwezidakamizwa kungahanjiswa ngqo kwisiza se-tumor, ngokunamandla okhulisa ukusebenza kahle kokwelapha.
• Ukwelashwa okwenziwe umuntu: Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza Ingalinganiswa kwizici ezithile zomdlavuza wesiguli, okuholela ezinhlelweni zokwelashwa ezisebenza ngempumelelo nokwenziwe ngezifiso.
• Ukunqoba Ukumelana Nezidakamizwa: -Nye Ukulethwa kwezidakamizwa okuhlosiwe komdlavuza Amasistimu anganqoba izindlela zokumelana nezidakamizwa, okwenza amaseli womdlavuza athambekele ekwelashweni.
