Histologie vh verdedigingssysteem of immuunstelsel (1)

1. Inleiding
A. Vrij oppervlak

 Hoornlaag (huid)
 Lysozyme (speeksel)
 pH (vagina)
 Mucus (luchtwegen)


B. Niet-specifieke cellulaire reacties

 Als 1e barrière doorbroken is
o Fagocytose bacteriën (macrofagen en WBC)
o Antivirale stoffen (interferonen)
 Innate immunity (aangeboren)


C. Specifiek immuunsysteem

 Humorale immuniteit
o B-lymfocyten => Ig

 Cellulaire immuniteit
o T-lymfo, door antigenen gestimuleerd

 Samen adaptive immunity (verworven)

 Lymfocyten in netwerk v reticulair bindweefsel
o Reticulumcellen
o Reticulinevezels

Uitz: Thymus – tss epitheliale reticulaire cellen

 Primair lymfoïde organen
o Beenmerg
- B-lymfo (Bursa v Fabricius bij vogels)

o Thymus
- T-lymfo

, 2. Primair lymfoïde organen




2.1 Beenmerg

 Bloedvormend + primair lymfoïd orgaan
 Gemeenschappelijke pluripotente stamcel: ontstaan lymf, meyel en megakaryo progenitorcel
 Multipotente stamcellen: myeloïde, erythroïde/megakaryocyte en lymfoïde progenitorcellen

 Myeloïde en erythroïde/megakaryocyte elementen
o Granulocyten, monocyten, erythrocyten, megakaryocyten (bloedplaatjes)
- Afname celvolume, wijziging kern/cytoplasmaverh, toename heterochromatine
o Volledige ontw in beenmerg

 Lymfoïde elementen
o Diff tot T-lymfo in thymus
- Antigen onafh deling en diff tot T en B in prim lymfoïde organen
- Antigen afh deling: secundair lymfoïde (milt, lymfeknopen, lymfo-epitheliale
organen)

o BCR= B cell receptor / TCR = Tcell receptor
- T cell heeft APC nodig (antigeen pres cell)
- B cell kan direct antigen herkennen



 Rode beenmerg
o Hematopoietisch actief
o Stroma: losse reticulumcellen en vezels
o 80-90% hematopoietische cellen
- Veel meer WBC dan RBC (door lange levensduur RBC)
o 10-20% reticulum-, vet- en plasmacellen (rijpe B), osteoblasten en osteoclasten
o Bloedvaten (sinusoïden)

 Gele beenmerg
o Vnl vetcellen
o Bij volwassene: rood beenmerg enkel nog in platte beenderen (schedel, sternum,…)

 Grote roze vlek: megakaryocyt
