Table 4.

Molecular factors in peri-implantitis and their function [84,85,86,87,88,89,90,91].

Cytokine Function
Interleukin-6 Stimulating acute phase protein synthesis, neutrophils production, fever mediation, B-cell growth stimulation
Interleukin-1α Part of epithelial barrier, epithelium integrity preservation
Interleukin-1β Modulating inflammatory response, pyrogen, pain hypersensitivity, cell proliferation
Tumor Necrosis Factor α Immune cells modulation, cell signaling, inflammation regulation, response to bacterial lipopolysaccharide
Interleukin-8 Neutrophil chemotaxis, phagocytosis stimulation
Interleukin-17 Recruitment of immune cells (mainly neutrophils and monocytes) via chemokines, promotes inflammatory responses of IL-1β and TNF-α
Interleukin-10 Anti-inflammatory agent, blocks NFkB activity resulting in decrease in osteoclasts formation, TNF-α regulation
MMP-8 Catalyzes the degradation of collagen type III and I
MMP-2 Collagen type IV degradation, cell-cell clustering
MMP-9 Collagen type IV and V degradation, cooperation with MMP-2 in ECM remodeling
MMP-7 Gelatin, fibronectin and proteoglycan degradation, probably plays role in wound healing
MMP-13 Collagen type I, II and III degradation, tissue remodeling
TIMP-1 MMPs inhibition, cell proliferation promotion
TIMP-2 MMPs inhibition, complements TIMP-1 in maintaining tissues hemostasis
RANKL Bone remodeling and regeneration control, cell proliferation, with RANK binding promotes osteoclasts formation and maturation
Osteoprotegrin Suppression of osteoclasts formation by competitive binding to RANK
