Bovine lactoferrin inhibits Plasmodium berghei growth by binding to heme. Sci Rep 2024; 14:20344.

Abstract
Bovine lactoferrin (bLF) is a 77 kDa glycoprotein that is abundant in bovine breast milk and exerts various bioactive functions, including antibacterial and antiviral functions. Few studies have explored bLF activity against parasites. We found that bLF affects hemozoin synthesis by binding to heme, inhibiting heme iron polymerization necessary for Plasmodium berghei ANKA survival in infected erythrocytes, and also binds to hemozoin, causing it to disassemble. In a challenge test, bLF administration inhibited the growth of murine malaria parasites compared to untreated group growth. To determine whether the iron content of bLF affects the inhibition of malaria growth, we tested bLFs containing different amounts of iron (apo-bLF, native-bLF, and holo-bLF), but found no significant difference in their effects. This indicated that the active sites were located within the bLFs themselves. Further studies showed that the C-lobe domain of bLF can inhibit hemozoin formation and the growth of P. berghei ANKA. Evaluation of pepsin degradation products of the C-lobe identified a 47-amino-acid section, C-1, as the smallest effective region that could inhibit hemozoin formation. This study highlights bLF's potential as a novel therapeutic agent against malaria, underscoring the importance of its non-iron-dependent bioactive sites in combating parasite growth.

Abstract
Ulcerative colitis (UC) is a kind of inflammatory bowel disease (IBD) that often recurs and is difficult to cure, and no drugs with few side effects are available to treat this disease. LfcinB is a small molecular peptide obtained by the hydrolysis of bovine lactoferrin in the digestive tract of animals. It has strong antibacterial and anti-inflammatory activities. However, direct evidence that LfcinB improves the condition of colitis in mice is rarely reported. In this study, UC was induced in mice by adding 2.5% dextran sulfate (DSS) to drinking water and LfcinB was orally administered. The results showed that oral administration of LfcinB improved colonic tissue damage and inflammatory cell infiltration, increased the expression of tight junction proteins, and down-regulated the phosphorylation of proteins related to the NF-κB/MAPK inflammatory signalling pathway in mice. It also significantly suppressed the relative abundance of potentially pathogenic bacteria (Bacteroides, Barnesiella and Escherichia) in the intestinal flora. In conclusion, oral administration of LfcinB significantly alleviated DSS-induced UC. This may be related to the regulation of inflammatory signalling pathways and gut microbial composition by LfcinB.

Abstract
In this article, we review the benefits of application of colostrum and colostrum-derived proteins in animal models and clinical trials that include chemotherapy with antimetabolic drugs, radiotherapy and surgical interventions. A majority of the reported investigations was performed with bovine colostrum (BC) and native bovine or recombinant human lactoferrin (LF), applied alone, in nutraceutics or in combination with probiotics. Apart from reducing side effects of the applied therapeutics, radiation and surgical procedures, BC and LF augmented their efficacy and improved the wellness of patients. In conclusion, colostrum and colostrum proteins, preferably administered with probiotic bacteria, are highly recommended for inclusion to therapeutic protocols in cancer chemo- and radiotherapy as well as during the surgical treatment of cancer patients.

Abstract
Low back pain (LBP) is a common problem worldwide, resulting in great patient suffering and great challenges for the social health system. Intervertebral disc (IVD) degeneration (IVDD) is widely acknowledged as one of the key causes of LBP. Accumulating evidence suggests that aberrant pyroptosis of IVD cells is involved in the pathogenesis of IVDD progression, however, the comprehensive roles of pyroptosis in IVDD have not been fully established, leaving attempts to treat IVDD with anti-pyroptosis approaches questionable. In this review, we summarize the characteristics of pyroptosis and emphasize the effects of IVD cell pyroptosis on the pathological progression of IVDD, including secretion of cytokines, nucleus pulposus cell apoptosis and autophagy, accelerated extracellular matrix degradation, annulus fibrosus rupture, cartilage endplate calcification, vascularization, sensory and sympathetic fiber neoinnervation, and infiltrating lymphatic vessels. Finally, we discuss several interventions used to treat IVDD by targeting pyroptosis. This review provides novel insights into the crucial role of IVD cell pyroptosis in IVDD pathogenesis, and could be informative for developing novel therapeutic approaches for IVDD and LBP.

Abstract
Bovine lactoferrin peptide has been shown to be a broad-spectrum antimicrobial peptide. Based on the relationship between the structure and function of antimicrobial peptides, the antimicrobial peptide databases and protein analysis software were used to optimize the design of bovine lactoferricin peptide (LfcinB). The designed bovine lactoferricin-derived peptide (LfcinBD) gene fragment was inserted into a pPIC9K-His plasmid to construct a recombinant expression vector. After linearization of the Recombinant plasmid, Pichia pastoris GS115 cells were transfected with linearized recombinant plasmid by using electroporation and LfcinBD gene expression was induced with methanol. After the fermentation, supernatant was separated by low-temperature high-speed centrifugation. Ultrafiltration and freeze drying of the fermentation supernatant were performed, purified. Experimental results showed that the LfcinBD had stronger bacteriostatic activity against Staphylococcus aureus than the natural bovine lactoferrin peptide (LfcinB) produced under the same fermentation conditions. The effective expression of the optimized bovine lactoferricin-derived peptide was detected using SDS-PAGE electrophoresis. This study lays the foundation for further exploration to improve the biological activities of antimicrobial peptides.
