Langerhansova ćelija (LC) je tkivno rezidentna dendritska ćelija kože.^[2] Ove ćelije sadrže organele zvane Birbeckove granule. Prisutne su u svim slojevima epiderme i najistaknutiji su u stratum spinosum.^[3] Javljaju se i u papilskoj dermi posebno oko krvnih sudova,^[3] kao i u usnoj sluzokoži, prepuciju i vaginskom epitelu. Mogu se naći u drugim tkivima, kao što su limfni čvorovi, posebno u vezi sa stanjem histiocitoza Langerhansovih ćelija (LCH).

Funkcija

U kožnim infekcijama, lokalne Langerhansove ćelije preuzimaju i obrađuju mikrobne antigene da bi postale potpuno funkcionalne ćelije koje prezentiraju antigen.^[4]

Općenito, makrofagi koji žive u tkivu uključeni su u imunološku homeostazu i unos apoptotskih tijela. Međutim, Langerhansove ćelije također mogu poprimiti fenotip dendritske ćelije i migrirati u limfni čvor da bi stupile u interakciju s nevinim T-ćelijama.

Langerhansove ćelije potieču od primitivnih eritro-mijeloidnih progenitora koji nastaju u žumančanoj vrećici izvan embriona u prvom tromjesečju trudnoće, a pod normalnim okolnostima opstaju cijeli život, obnavljajući se lokalnom proliferacijom kao neophodno. Ako koža postane ozbiljno upaljena, možda zbog infekcije, krvni monociti se regrutuju u zahvaćenu regiju i diferenciraju u zamjenske LC.^[5]

Langerin je protein u Langerhansovim ćelijama,^[6] dendritskim ćelijama.^[7]

LC-ovi sadrže veliku količinu kanabinoidnih receptora tip 2 (CB2), koji aktivacijom putem agonista, smanjuje i regrutaciju eozinofila i otoka uha kod hroničnog kontaktnog dermatitisa izazvanog ponovljenim izazivanjem.^[8]

Opadanje funkcije tokom starenja

Tokom starenja kapacitet Langerhansovih ćelija za migraciju opada.^[9] To ugrožava imunost i izlaže kožu zaraznim bolestima i raku.

Historija

Langerhansove ćelije su nazvane po Paulu Langerhansu, njemačkom ljekaru i anatomu, koji je otkrio ćelije u dobi od 21 godine dok je bio student medicine.^[10] Zbog njihovog izgleda poput dendrita, on je greškom identificirao ćelije kao dio nervnog sistema.^[11]
