Le cellule natural killer (NK) sono globuli bianchi che distruggono le cellule infette e malate, come le cellule tumorali. Sono anche un tipo di linfociti, come le cellule B e le cellule T. Le cellule NK uccidono direttamente le cellule tumorali attraverso vari meccanismi. | Cronache di scienza

L’IMPORTANZA DELLE CELLULE NK L'immunoterapia del cancro ha messo in luce l'importanza delle cellule NK (Natural Killer), componenti essenziali del nostro sistema immunitario, capaci di eliminare cellule infette o cancerose attraverso il rilascio di granuli citotossici. Questi granuli contengono perforine e granzimi, che agiscono sulle cellule cancerose in più modi, tra cui inducendo la morte cellulare per apoptosi o necrosi. L'apoptosi, descritta come un "suicidio cellulare" programmato, è un p
