Analysis of the effect of CDIP-2 in an ovalbumin (OVA)-induced lung inflammation murine model. BALB/c mice were sensitized and challenged with OVA following the protocol described in Methods. Controls using saline solution (SS) and chemokine (C-C motif) ligand 13 (CCL13)-derived peptide (CDP)-1 treatment and challenge were performed as described. Histological analysis of haematoxylin and eosin-stained lung tissue sections of (a,e) SS-treated mice, (b,f) OVA-sensitized, OVA-challenged and SS-treated, (c,g) OVA-sensitized, OVA-challenged and CDIP-2-treated mice, (d,h) OVA-sensitized, OVA-challenged and CDP-1-treated mice. Histological analysis of periodic acid Schiff-stained lung tissue sections. (i) SS-treated mice, (j) OVA-sensitized, OVA-challenged and SS-treated, (k) OVA-sensitized OVA-challenged and CDIP-2-treated mice, (l) OVA-sensitized, OVA-challenged and CDP-1 treated.
