Figure Lengend Snippet: Histological skin sections of mouse groups stained with haematoxylin and eosin at 10× magnification. Group 1 (control) showed normal skin structures, including the keratin skin layers (yellow line), epidermis (red line), dermis (green line), and sebaceous glands (blue line). Group II (IMQ group) tissue demonstrated hallmarks of psoriasis, including marked epidermal inflammatory processes (yellow line), prominent rete processes thinning (red line), intense hyperkeratotic lesions (green line), and marked acanthotic alterations (blue line). Group III (CLO group) showed mild psoriasis inflammation (yellow line), moderate rete peg lengthening (red line), mild hyperkeratotic lesions (green line), and mild acanthotic changes (blue line). Mice subjected to 1% VNP (group IV) exhibited modest inflammation (yellow line), mild extension of rete pegs (red line), minor hyperkeratotic lesions (green line), and modest acanthotic modifications (blue line). Group V (3% VNP) mice had mild skin inflammation (yellow line), absence of rete ridge processes (red line), absence of hyperkeratotic signs (green line), and absence of acanthotic alterations (blue line). Mice in group V (CLO + VNP) displayed modest epidermal inflammation (yellow line), absence of rete ridge processes (red line), absence of hyperkeratotic signs (green line), and a lack of acanthotic changes (blue line).
