Inflama\u021bia este modul prin care organismul lupt\u0103 cu infec\u021biile \u0219i, \u00een mod normal, ajut\u0103 la vindecare. Dar atunci c\u00e2nd devine prea puternic\u0103, aceasta poate afecta \u021besuturile s\u0103n\u0103toase \u0219i poate complica evolu\u021bia bolii. \u00cen cazuri grave, duce la sepsis, o stare periculoas\u0103 \u00een care reac\u021bia exagerat\u0103 a organismului afecteaz\u0103 circula\u021bia s\u00e2ngelui, iar organele nu mai primesc suficient oxigen \u0219i pot ceda.<\/p>\n

Particulele care amplific\u0103 inflama\u021bia<\/h2>\n

Particulele despre care vorbe\u0219te studiul citat de ScienceAlert poart\u0103 numele de vezicule extracelulare bacteriene \u0219i sunt structuri microscopice, asem\u0103n\u0103toare unor mici \u201ebule\u201d. Bacteriile le elibereaz\u0103 \u00een mod natural, dar \u00een cantit\u0103\u021bi mult mai mari atunci c\u00e2nd sunt expuse la anumite antibiotice.<\/p>\n

Aceste particule transport\u0103 proteine, toxine \u0219i alte substan\u021be \u0219i influen\u021beaz\u0103 modul \u00een care reac\u021bioneaz\u0103 sistemul imunitar, av\u00e2nd efecte puternice asupra organismului.<\/p>\n

Atunci c\u00e2nd ajung \u00een s\u00e2nge, aceste vezicule pot activa celulele care c\u0103ptu\u0219esc vasele de s\u00e2nge \u0219i pot declan\u0219a o reac\u021bie imunitar\u0103 mai puternic\u0103 dec\u00e2t este necesar. \u00cen loc s\u0103 ajute la vindecare, aceast\u0103 reac\u021bie poate accentua inflama\u021bia \u0219i poate complica evolu\u021bia infec\u021biei.<\/p>\n

Cum influen\u021beaz\u0103 antibioticele acest proces<\/h2>\n

Antibioticele ac\u021bioneaz\u0103 \u00een moduri diferite. Unele atac\u0103 peretele bacteriilor, sl\u0103bindu-l p\u00e2n\u0103 c\u00e2nd acestea se rup \u0219i mor. Altele blocheaz\u0103 procesele interne ale bacteriilor, cum ar fi producerea proteinelor sau replicarea ADN-ului. \u00cen acela\u0219i timp \u00eens\u0103, ele supun bacteriile unui stres puternic.<\/p>\n

Studiul arat\u0103 c\u0103 acest stres determin\u0103 bacteriile s\u0103 elibereze mai multe vezicule extracelulare, \u00eenc\u0103rcate cu substan\u021be care amplific\u0103 inflama\u021bia.<\/p>\n

Pentru a analiza acest efect, cercet\u0103torii au expus bacteria E. coli la mai multe tipuri de antibiotice \u0219i au m\u0103surat cantitatea de vezicule produs\u0103.<\/p>\n

Diferen\u021bele apar \u00een reac\u021bia bacteriilor la antibiotice<\/h2>\n

Rezultatele au ar\u0103tat c\u0103 nu toate antibioticele au acela\u0219i efect. Cele care afecteaz\u0103 peretele bacterian \u2014 inclusiv o clas\u0103 larg utilizat\u0103, numit\u0103 beta-lactamine \u2014 au determinat o cre\u0219tere semnificativ\u0103 a num\u0103rului de vezicule eliberate. Aici intr\u0103, de exemplu, antibiotice cunoscute precum penicilinele, cefalosporinele sau carbapenemele.<\/p>\n

\u00cen schimb, antibioticele care ac\u021bioneaz\u0103 asupra proteinelor sau ADN-ului bacterian au avut un efect mult mai redus asupra acestui proces.<\/p>\n

Diferen\u021ba observat\u0103 \u00een efectul antibioticelor sugereaz\u0103 c\u0103 modul \u00een care sunt distruse bacteriile influen\u021beaz\u0103 \u0219i modul \u00een care reac\u021bioneaz\u0103 \u00eenainte de a muri. Ca r\u0103spuns la deteriorare, atunci c\u00e2nd structura lor este afectat\u0103, ele pot elibera mai multe astfel de particule.<\/p>\n

Pot schimba efectul tratamentului<\/h2>\n

Cercetarea nu arat\u0103 c\u0103 antibioticele agraveaz\u0103 infec\u021biile \u0219i nu pune sub semnul \u00eentreb\u0103rii utilizarea lor. Ele r\u0103m\u00e2n esen\u021biale \u00een medicin\u0103.<\/p>\n

\u00cen schimb, sugereaz\u0103 c\u0103 tipul de antibiotic poate influen\u021ba nu doar eficien\u021ba tratamentului, ci \u0219i reac\u021bia organismului, \u00een special nivelul de inflama\u021bie.<\/p>\n

Acest lucru ar putea fi relevant mai ales \u00een cazurile severe, unde controlul inflama\u021biei este esen\u021bial.<\/p>\n

\u00cen acela\u0219i timp, studiul arat\u0103 c\u0103 bacteriile nu sunt doar \u021binte pasive ale tratamentului. \u201eEle reac\u021bioneaz\u0103 activ la antibiotice\u201d, a explicat Panteha Torabian, doctorand\u0103 \u00een inginerie biomedical\u0103 \u0219i chimic\u0103 la Institutul de Tehnologie din Rochester (Rochester Institute of Technology), iar aceste reac\u021bii \u201epot influen\u021ba nivelul inflama\u021biei din organism\u201d.<\/p>\n

Cercet\u0103torii spun c\u0103 sunt necesare studii suplimentare pentru a \u00een\u021belege cum se traduc aceste mecanisme \u00een cazul pacien\u021bilor.<\/p>\n","protected":false},"excerpt":{"rendered":"
