És un mecanisme clau de la immunitat innata per a eliminar microorganismes, restes celulars i cossos estranys.<br /> <br /> == Tipus de fagòcits ==<br /> Els principals fagòcits en hòmens són:<br /> * [[Neutròfil|Neutròfils]]: Són els primers en arribar al lloc de l&#039;infecció. Tenen una vida curta.<br /> * Macròfacs: Deriven dels [[monòcit|monòcits]] de la sanc. Estan en els teixits i tenen una vida llarc. S&#039;encarreguen de fagocitar restes celulars i presentar antígens.<br /> * Cèlules dendrítiques: La seua funció principal és presentar antígens als [[limfòcit|limfòcits]] T per a iniciar la resposta immune adaptativa.<br /> <br /> == Fases del procés ==<br /> * Quimiotaxis: El fagòcit es dirigix cap a la partícula atret per senyals químics, com les citocines.<br /> * Adherència: El fagòcit reconeix i es pega a la partícula. Este procés millora molt en l&#039;opsonisació, a on anticossos o proteïnes del complement recobrixen el microorganisme.<br /> * Ingestió: La membrana del fagòcit rodeja la partícula i la introduïx dins del citoplasma, formant un fagosoma.<br /> * Digestió: El fagosoma es fusiona en els lisosomes, que contenen enzims digestius i substàncies bactericides. Es forma el fagolisosoma i la partícula és destruïda.<br /> * Exocitosis: Les restes no digeribles són expulsades de la cèlula.<br /> <br /> == Importància biològica ==<br /> === Defensa contra infeccions ===<br /> És la primera llínea de defensa contra bactèries i fongs.<br /> <br /> === Eliminació de cèlules mortes ===<br /> Els macròfacs fagociten diàriament millons de cèlules velles, com els eritròcits.<br /> <br /> === Inici de la resposta adaptativa ===<br /> En presentar fragments dels patògens, conecta la immunitat innata en la adquirida.<br /> <br /> == Alteracions == <br /> * Defectes en la fagocitosis produïxen immunodeficiències. Un eixemple és la malaltia granulomatosa crònica, a on els fagòcits no poden produir les substàncies necessàries per a matar als microorganismes ingerits, lo que causa infeccions greus i de repetició.<br /> <br /> == Vore també ==<br /> * Neutròfil<br /> * Macròfac<br /> * Immunitat innata<br /> * Inflamació<br /> <br /> == Referències ==<br /> * Abbas, Lichtman i Pillai. &#039;&#039;Inmunologia celular i molecular&#039;&#039;. 10ª ed.<br /> * Guyton i Hall. &#039;&#039;Tractat de Fisiologia Mèdica&#039;&#039;. 14ª ed.<br /> * Farreras-Rozman. &#039;&#039;Medicina Interna&#039;&#039;<br /> <br /> == Bibliografia ==<br /> * Diccionari General de la Llengua Valenciana.
