The role of lactoferrin in bone remodeling: evaluation of its potential in targeted delivery and treatment of metabolic bone diseases and orthopedic conditions.

Abstract
Lactoferrin (Lf) is a multifunctional protein that is synthesized endogenously and has various biological roles including immunological regulation, antibacterial, antiviral, and anticancer properties. Recently, research has uncovered Lf's critical functions in bone remodeling, where it regulates the function of osteoblasts, chondrocytes, osteoclasts, and mesenchymal stem cells. The signaling pathways involved in Lf's signaling in osteoblasts include (low density lipoprotein receptor-related protein - 1 (LRP-1), transforming growth factor β (TGF-β), and insulin-like growth factor - 1 (IGF-1), which activate downstream pathways such as ERK, PI3K/Akt, and NF-κB. These pathways collectively stimulate osteoblast proliferation, differentiation, and mineralization while inhibiting osteoclast differentiation and activity. Additionally, Lf's inhibitory effect on nuclear factor kappa B (NF-κB) suppresses the formation and activity of osteoclasts directly. Lf also promotes chondroprogenitor proliferation and differentiation to chondrocytes by activating the mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt)signaling pathways while inhibiting the expression of matrix-degrading enzymes through the suppression of the NF-κB pathway. Lf's ability to stimulate osteoblast and chondrocyte activity and inhibit osteoclast function accelerates fracture repair, as demonstrated by its effectiveness in animal models of critical-sized long bone defects. Moreover, studies have indicated that Lf can rescue dysregulated bone remodeling in osteoporotic conditions by stimulating bone formation and suppressing bone resorption. These beneficial effects of Lf on bone health have led to its exploration in nutraceutical and pharmaceutical applications. However, due to the large size of Lf, small bioactive peptides are preferred for pharmaceutical applications. These peptides have been shown to promote bone fracture repair and reverse osteoporosis in animal studies, indicating their potential as therapeutic agents for bone-related diseases. Nonetheless, the active concentration of Lf in serum may not be sufficient at the site requiring bone regeneration, necessitating the development of various delivery strategies to enhance Lf's bioavailability and target its active concentration to the site requiring bone regeneration. This review provides a critical discussion of the issues mentioned above, providing insight into the roles of Lf in bone remodeling and the potential use of Lf as a therapeutic target for bone disorders.

Abstract
Bone and joint infections are a rare but serious problem worldwide. Lactoferrin’s antimicrobial and antibiofilm activity coupled with its bone-regenerating effects may make it suitable for improving bone and joint infection treatment. However, free lactoferrin (LF) has highly variable oral bioavailability in humans due to potential for degradation in the stomach and small intestine. It also has a short half-life in blood plasma. Therefore, encapsulating LF in nanocarriers may slow degradation in the gastrointestinal tract and enhance LF absorption, stability, permeability and oral bioavailability. This review will summarize the literature on the encapsulation of LF into liposomes, solid lipid nanoparticles, nanostructured lipid carriers, polymeric micro and nanoparticles and hydroxyapatite nanocrystals. The fabrication, characterization, advantages, disadvantages and applications of each system will be discussed and compared.

Abstract
OBJECTIVE To investigate the effects of different lactoferrin concentrations on mid-palatal suture bone remodeling during palatal expansion and relapse in rats. MATERIALS AND METHODS Thirty-two 5-week-old male Wistar rats were randomly divided into four groups: EO (expansion only), E+LF1 (expansion plus 10 mg/kg/day daily LF), E+LF2 (expansion plus 100 mg/kg/day daily LF), and E+LF3 (expansion plus 1 g/kg/day daily LF). Thereafter, micro-computed tomography and micro-morphology of the mid-palatal suture were analyzed on day 7 and day 14, respectively. RESULTS The arch widths were increased in all the four groups after expansion, and there was no significant difference among them on day 7. After relapse, however, the arch width in the E+LF3 group was significantly larger compared with EO group. In E+LF3 group and E+LF2 group, new bone formation and osteoblast number were enhanced with up-regulated expression of osteocalcin and collagen type I, while the expression of cathepsin K-positive cells was downregulated in E+LF3 group. CONCLUSION Lactoferrin gavage administration might increase the stability of palatal expansion and reduce relapse in a concentration-dependent manner by enhancing bone formation and inhibiting resorption. LF administration may be promising for optimizing the maxillary expansion outcome.

Chen Y, Zhou T, Zhang HH, Kang N. Bovine lactoferrin inhibits alveolar bone destruction in an orthodontic rat model with periodontitis. Ann Anat 2021; 237:151744. [PMID: 33895284 DOI: 10.1016/j.aanat.2021.151744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 03/10/2021] [Accepted: 04/01/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE We aimed to evaluate the effect of bovine lactoferrin (bLF) on alveolar bone destruction and remodelling under orthodontic force (OF) in periodontitis-affected rats. MATERIAL AND METHODS After establishing the periodontitis-affected rat model with lipopolysaccharides (LPS), the left maxillary first molars were moved orthodontically under a force of 0.2N. Based on saline or bLF gavage, 54 Sprague-Dawley (SD) rats were randomized into 5 groups: A (blank), P1 (LPS+OF+bLF), P2 (LPS+OF+saline), C1 (OF+bLF), and C2 (OF+saline). Animals were evaluated using micro-computed tomography (micro-CT) followed by haematoxylin and eosin (H&E) and tartrate-resistant acid phosphatase (TRAP) staining, and the LF level was determined using ELISA in the gingival crevicular fluid (GCF) of the experimental teeth. Immunohistochemistry helped to detect expression changes in RANKL, OPG and COX-2. RESULTS Micro-CT results indicated that compared with group P2, trabecular number (Tb.N) and trabecular thickness (Tb.Th) in group P1 were higher and bone surface/bone volume (BS/BV) was lower on day 14, while trabecular separation (Tb.Sp) decreased significantly on Day 5 and Day 14 after bLF gavage (P<0.05). This was supported by changes in H&E and TRAP staining. bLF down-regulated RANKL level at both timepoints and up-regulated OPG level on Day 14 in periodontitis rats (P<0.05). The significant changes mentioned above were not observed between group C1 and C2 (P>0.05). No significant change in COX-2 levels were observed in any group (P>0.05). The lactoferrin level in GCF increased significantly after bLF gavage (P<0.05). CONCLUSION Bovine lactoferrin inhibited LPS-induced bone destruction, but the bone healing effect was independent of orthodontic aseptic inflammatory bone remodelling.

Abstract
Lactoferrin (Lf), an iron-binding multifunctional glycoprotein belonging to the transferrin family, is present in most biological secretions and reaches particularly high concentrations in colostrum and breast milk. A key function of lactoferrin is non-immune defence and it is considered to be a mediator linking innate and adaptive immune responses. Lf from bovine milk (bLf), the main Lf used in human medicine because of its easy availability, has been designated by the United States Food and Drug Administration as a food additive that is generally recognized as safe (GRAS). Among the numerous protective activities exercised by this nutraceutical protein, the most important ones demonstrated after its oral administration are: Antianemic, anti-inflammatory, antimicrobial, immunomodulatory, antioxidant and anticancer activities. All these activities underline the significance in host defence of bLf, which represents an ideal nutraceutical product both for its economic production and for its tolerance after ingestion. The purpose of this review is to summarize the most important beneficial activities demonstrated following the oral administration of bLf, trying to identify potential perspectives on its prophylactic and therapeutic applications in the future.

Abstract
Among the multiple properties exhibited by lactoferrin (Lf), its involvement in bone regeneration processes is of great interest at the present time. A series of in vitro and in vivo studies have revealed the ability of Lf to promote survival, proliferation and differentiation of osteoblast cells and to inhibit bone resorption mediated by osteoclasts. Although the mechanism underlying the action of Lf in bone cells is still not fully elucidated, it has been shown that its mode of action leading to the survival of osteoblasts is complemented by its mitogenic effect. Activation of several signalling pathways and gene expression, in an LRPdependent or independent manner, has been identified. Unlike the effects on osteoblasts, the action on osteoclasts is different, with Lf leading to a total arrest of osteoclastogenesis. Due to the positive effect of Lf on osteoblasts, the potential use of Lf alone or in combination with different biologically active compounds in bone tissue regeneration and the treatment of bone diseases is of great interest. Since the bioavailability of Lf in vivo is poor, a nanotechnology- based strategy to improve the biological properties of Lf was developed. The investigated formulations include incorporation of Lf into collagen membranes, gelatin hydrogel, liposomes, loading onto nanofibers, porous microspheres, or coating onto silica/titan based implants. Lf has also been coupled with other biologically active compounds such as biomimetic hydroxyapatite, in order to improve the efficacy of biomaterials used in the regulation of bone homeostasis. This review aims to provide an up-to-date review of research on the involvement of Lf in bone growth and healing and on its use as a potential therapeutic factor in bone tissue regeneration.

Abstract
INTRODUCTION The aim of this study was to investigate the effect of lactoferrin (LF) on bone resorption of rats' midpalatal sutures during rapid palatal expansion. METHODS Sixty male 5-week-old Wistar rats were randomly divided into 3 groups: expansion only (EO), expansion plus LF (E + LF), and sham device (control). RESULTS Microcomputed tomography showed that the bone volume/tissue volume ratio and the relative bone mineral density of the suture bone were significantly increased in the E + LF group compared with the EO group. Histochemical staining suggested that the activity of osteoblast-like cells and the amount of new bone formation were stimulated in the E + LF group whereas the activity of osteoclasts showed no obvious difference between groups. On the other hand, the immunohistochemical and the real-time polymerase chain reaction results showed that the expressions of receptor activator of nuclear factor kappa B ligand and osteoprotegerin had no significant difference between the EO and E + LF groups. CONCLUSIONS These findings demonstrated that LF could stimulate bone volume and bone density in midpalatal sutures during the suture remodeling process under tensile force. However, this enhancement effect was not caused by the reduction of bone resorption.

Abstract
Bovine lactoferrin (bLF) is a multifunctional protein with anti-inflammatory, antibacterial, antiviral, anti-tumour and immunoregulatory effects. The present study was conducted to evaluate the anti-inflammatory and anti-tumour effects of liposomal bLF (LbLF) in a 1,2-dimethylhydrazine (DMH)/dextran sulphate sodium (DSS)-induced model of carcinogenesis in F344 rats. F344 rats were randomly divided into three groups: Control (water), 500 or 1,000 mg/kg/day LbLF; additionally, the rats were injected with DMH (20 mg/kg) once per week for 8 consecutive weeks, after one week of drinking water containing 1% DSS. All rats were sacrificed at 25 weeks. The tissues were examined for the presence of aberrant crypt foci (ACF) and subjected to histopathological analysis. Additionally, human colon cancer cells were utilised to investigate the effect of LbLF on proliferation and inflammation. Rats from the 500 and 1,000 mg/kg/day LbLF groups harboured significantly fewer colon ACF, adenomas and adenocarcinomas than the rats from the control group. Lastly, it was demonstrated that LbLF inhibits cell growth and TNF-α mRNA expression. These data support the hypothesis that LbLF affects colorectal carcinogenesis by suppressing inflammation and cell proliferation in rats.

Abstract
There is an urgent clinical need for an effective therapeutic agent to treat neuropathic pain. This study explored whether intrathecal administration of bovine lactoferrin (bLF), in combination with signal transduction pathway inhibition or an inflammatory cytokine production, results in reduced allodynia/hyperalgesia in the whisker pad area following mental nerve transection (MNT) in rats. Rats were intrathecally infused with bLF, lipopolysaccharide from Rhodobacter sphaeroides (LPS-RS), an antagonist of Toll-like receptor 4 (TLR4), or interleukin (IL)-18 binding protein (BP). bLF attenuated allodynia/hyperalgesia and blocked upregulation of phosphorylated (p)-p38 mitogen-activated protein kinase (MAPK), p-nuclear factor (NF)-κB p65, p-IκB kinase, and IL-18 in the trigeminal subnucleus caudalis (Vc). Microglia expressed p-p38 and astrocytes expressed p-NF-κB p65 in the Vc following MNT. LPS-RS had the same effects as bLF, except for attenuation of p-NF-κB p65. IL-18BP attenuated allodynia/hyperalgesia and IL-18 upregulation in the Vc. These results suggest that bLF suppresses IL-18 production, which is involved in allodynia/hyperalgesia following MNT, by inhibiting TLR4-derived p38 MAPK activation in microglia. Additionally, binding of bLF to tumor necrosis factor receptor-associated factor 6 might result in inhibition of p38 MAPK and NF-κB activation. The findings suggest that bLF could serve as a potent therapeutic agent for neuropathic pain.

J Periodontal Res 2017; 52:725-733.

Abstract
BACKGROUND AND OBJECTIVES It is recognized that orthodontic force (OF) has an aggravating effect on the progression of destructive periodontitis if periodontitis have not been well controlled. However, the underlying mechanism is not completely clear. This study was to investigate the effect of antibiotic administration on OF-aggravated, ligature-induced experimental periodontitis in mice. MATERIAL AND METHODS C57BL/6 mice (male, 8 wk old) were divided into three groups (n = 8). Silk ligatures (SL) were tied around the maxillary right (group 1) or both (groups 2 and 3) first molars on day 0, removed on day 8 and systemic antibiotics was administered through drinking water (group 3) since day 8. OF was applied on the maxillary right first molars since day 13 (groups 2 and 3). All mice were killed on day 20. RESULTS Total oral bacteria load was significantly higher in group 2 when compared to group 1 on day 20, whereas such count was greatly reduced in group 3 when antibiotics were administered. Periodontal bone loss was significantly increased on SL side vs. control side in group 1. Periodontal bone loss was significantly increased on OF + SL side vs. SL side in group 2 (p < 0.05) but not in group 3 when systemic antibiotics were administered. Gingival mRNA and protein expressions of receptor activator of nuclear factor kappa-B ligand/osteoprotegerin were significantly increased on OF + SL side vs. SL side in group 2 (p < 0.01) but not in group 3. However, comparable levels of tartrate-resistant acid phosphatase-positive cell formation within periodontal space and tooth movement were observed on OF + SL side in groups 2 and 3. CONCLUSION Our results suggest that reduction of oral bacterial load by antibiotic administration alleviate orthodontic force-aggravated periodontitis bone loss.

Abstract
There is a growing interest in the development of organic nanomaterials for biomedical applications. An increasing number of studies focus on the uses of nanomaterials with organic structure for regeneration of bone, cartilage, skin or dental tissues. Solid evidence has been found for several advantages of using natural or synthetic organic nanostructures in a wide variety of dental fields, from implantology, endodontics, and periodontics, to regenerative dentistry and wound healing. Most of the research is concentrated on nanoforms of chitosan, silk fibroin, synthetic polymers or their combinations, but new nanocomposites are constantly being developed. The present work reviews in detail current research on organic nanoparticles and their potential applications in the dental field.
