Fig. 2From: The impact of genetic manipulation of laminin and integrins at the blood–brain barrierThe molecular structure of laminin. Laminins are heterotrimers consisting of α (purple), β, (bright blue) and γ (grey blue) subunits of which 5α, 4β and 3 γ have been so far defined. Laminins are named according to their subunit composition; for instance, laminin-111 comprises the subunits α1, β1 and γ1Back to article page
