HEM13 Week 3

Plasma eiwitten: Eiwitten met een functie in bloed / plasma / serum

Aanmaak en afbraak
 Aanmaak in
o lever (vrijwel alle eiwitten)
o plasmacellen: immuunglobulinen
 Afbraak in
o mononucleare fagocyten systeem (MPS)

Algemene functies
 Transport
 Ontstekingsrespons / immunologische afweer = bescherming
 Waterdistributie (colloïd osmotische druk)




Modulewijzer Bijlage 5: Scheiden van eiwitten
Scheiding d.m.v. electroforese Verschillende soorten dragermateriaal




Eiwitindeling naar functie
 Transporteiwitten
 Acute fase-eiwitten
 Immuunglobulinen
 Signaaleiwitten
 Restanten van necrotische (kapotte) cellen

Transporteiwitten
 Albumine: 50% van het serumeiwit
molmassa 65.000 dalton
o Bindt o.a.
 apolaire stoffen: vetzuren
bilirubine
medicijnen
steroïden
 Ca2+ en H+

,  Metaaltransporters:
o ceruloplasmine (Cu+)
o transferrine (Fe2+)
 Hormoontransporters
o tyroxinebindend globuline (TBG)
o cortisolbindend eiwit (CBP)
o sexhormoon bindend eiwit (SHBG) etc.

Acute fase-eiwitten
Acutefase reactie => complex van systemische veranderingen die optreden bij
ontsteking

Verandering van concentraties van een aantal serumeiwitten
 Sommige worden significant meer aangemaakt (o.a. CRP en fibrinogeen => acute
fase-eiwitten
 Meestal worden andere eiwitten dan minder aangemaakt
o (b.v. albumine) => totale eiwitconcentratie blijft gelijk
 Activatoren van immuunrespons:
o C-reactieve eiwit (bindt aan celwand van pneumococcen)
 Remmers van (bacteriële) proteases:
o α1-antitrypsine
o α2-macroglubuline
 Eiwitten die stoffen binden, die voor de bacterie nodig zijn:
o ceruloplasmine (Cu)
o haptoglobine (heem+Fe)
 Complementeiwitten

Complementeiwitten
 Serie eiwitten die in het bloed en weefselvloeistoffen in inactieve vorm circuleren
 Ze vermeerderen de activiteit van de verworven afweer
 Stimulatie van inactieve eiwitten initieert cascade van reacties
o Resulteert in snelle activatie van componenten
 Drie routes van activatie
o Alternatieve route
o Lectine route
o Klassieke route
