Teknik floresan molekülleri kullanımı önemli bir azalma sunmaktadır ve 10-20 daha az T hücreleri ile karşılaştırıldığında birinci...

T-hücre bağışıklık sinapslarda ve T hücrelerinin fonksiyonel etkinlik onların bağlantı yapısal özelliklerinden bilimsel bilgi öncelikle hücre hatları kursundan üretti ve PB türetilmiş klonlar. Bu bulgular için birincil T hücreleri arasında bir ilişki ne derece elde kan veya insan lenfoid doku kalır belirsiz, lenfoid ve diğer dokularda bulunan T hücre sinaptik arabirimleri şu ana kadar analiz değil gibi. Önemlisi, gelişmekte olan verileri doku yerleşik ve lenfoid organ elde T hücreleri fenotip ve fonksiyonel etkinlik bu PB6,7göre önemli farklılıklar olabileceğini göstermektedir. Bu daha fazla daha iyi birincil insan T hücreleri T-hücre sinaptik arabiriminde özelliklerini anlamak gerek katılaşmış.
Bu amaçla, biz bize insan PB ve LN. izole az 105 birincil T hücreleri ile T-hücre/bilayer arayüzleri görüntüleme gerçekleştirmesini sağlayan çok kanallı akışı slaytlar içine yerleştirilmiş lipid bilayers istismar bir roman mini ölçek yaklaşım geliştirdik Bu roman tekniği daha iyi model ve in vivo hücre-hücre etkileşimleri anlamak için birincil insan T-hücre sinaptik arabirimleri biyofiziksel özelliklerini sağlar.
