    <ns1:description language="sr">Multipla skleroza (MS) je hronična inflamatorna i neurodegenerativna bolest centralnog
nervnog sistema (CNS) sa autoimunskom patogenezom. Najčešće pogađa populaciju
između 20-40 godina, češća je kod žena nego kod muškaraca, kao i u Evropi i Severnoj
Americi u odnosu na druge delove sveta. Iako još uvek nije jasno definisan uzrok
nastanka ove bolesti, smatra se da su u njenoj osnovi kompleksne interakcije između
različitih gena i faktora sredine.
Eksperimentalni autoimunski encefalomijelitis (EAE) je najkorišćeniji animalni model
MS-a. Indukuje se najčešće u glodarima i to imunizacijom, korišćenjem homogenata
tkiva CNS-a, mijelina ili nekih od proteina mijelina koji se mešaju sa adjuvansom.
Nakon imunizacije, CD4+ T-ćelije specifične za antigen CNS-a proliferišu i
diferenciraju se u drenirajućem limfnom čvoru, nakon čega dolazi do njihove migracije
i širenja po celom organizmu. Deo ćelija specifičnih za antigene nervnog sistema odlazi
u CNS, prolazi kroz krvno-moždanu barijeru i u perivaskularnom prostoru prepoznaje
antigen za koji je specifičan. Nakon susreta sa antigenom T-ćelije bivaju reaktivirane,
počinju da produkuju odgovarajuće citokine, aktiviraju lokalne ćelije i dalje privlače
inflamatorne ćelije u CNS. Na ovaj način nastaje inflamatorna reakcija koja za
posledicu ima uništavanje mijelinskog omotača, a u određenim slučajevima i aksona
dovodeći tako do neurodegeneracije.
Citokini predstavljaju bitne medijatore svakog inflamatornog procesa. IL-10 je antiinflamatorni
citokin sa osnovnom ulogom u zaštiti tkiva i ograničavanju preteranog
inflamatornog odgovora. Sa druge strane, TNF je predstavniik pro-inflamatorne grupe
citokina koji ima ključnu ulogu medijatora akutne i hronične sistemske inflamatorne
reakcije. Oba citokina su dosta proučavana u EAE modelu, gde se IL-10 u najširem
smislu smatra protektivnim, dok se TNF uglavnom smatra štetnim i odgovornim za
pojačavanje inflamatorne rekcije...</ns1:description>
    <ns1:description language="en">Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease of the
central nervous system (CNS) with a proposed autoimmune pathogenesis. It mainly
affects population between 20-40 years of age, more often women in comparison to men
Also, it is more often in Europe and north America comparing to other parts of the
world.. The cause of this disease is still not well defined, but it is thought to be complex
interaction between genes and different environmental factors.
Experimental autoimmune encephalomyelitis (EAE) is the most commonly used MS
animal model. It is mostly induced in rodents by using spinal cord homogenate, myelin
or some of the myelin’s proteins and mixing them with adjuvants. After the
immunization antigen specific CD4+ T cells proliferate and differentiate in draining
lymph nodes after which they migrate and spread all around the body. One part of the
antigen specific cells goes to CNS, crosses blood-brain barrier and enters the
perivascular space where it recognizes antigens which they are specific for. After
encountering the antigens T cells are reactivated and they start producing cytokines,
activate local cells and attract other inflammatory cells in to the CNS. This is how
inflammatory reaction begins leading to distraction of myelin sheet or even axons in
some cases, finally causing neurodegeneration.
Cytokines are important mediators of every inflammatory process. IL-10 is an antiinflammatory
cytokine with a primary role in tissue protection and restriction of
inflammatory response. On the other hand, TNF is a classical pro-inflammatory
cytokine which mediates acute and chronic systemic inflammatory reaction. The role of
both these cytokines has been well studied in EAE model, where IL-10 is considered to
be protective while TNF is mostly thought of as deleterious and responsible for
increasing the inflammatory reaction...</ns1:description>
