    Lactoferrin is a multifunctional glycoprotein naturally found in mammalian secretions, predominantly in colostrum and milk. As a key component of dairy foods, lactoferrin enhances viral protection and boosts human health, owing to its fundamental properties including antiviral, anti-inflammatory, and immune-modulatory effects. Importantly, the antiviral effect of lactoferrin has been shown against a range of viruses causing serious infections and threatening human health. One of the viruses that lactoferrin exerts significant antiviral effects on is the human papillomavirus (HPV), which is the most prevalent transmitted infection affecting a myriad of people around the world. Lactoferrin has a high potential to inhibit HPV via different mechanisms, including direct binding to viral envelope proteins or their cell receptors, thereby hindering viral entry and immune stimulation by triggering the release of some immune-related molecules through the body, such as lymphocytes. Along with HPV, lactoferrin also can inhibit a range of viruses including coronaviruses and hepatitis viruses in the same manner. Here, we overview the current knowledge of lactoferrin and its effects on HPV and other viral infections.

    (Mdpi, 2024) Bolat, Ecem; Karagoz, Zeynep; Alves, Jose Luiz de Brito; Neto, Jose Patrocinio Ribeiro Cruz; Witkowska, Anna Maria; El-Seedi, Hesham; Lombardo, Mauro
    Skin is a crucial organ for preserving the body's equilibrium. Like other parts of the body, skin also ages due to extrinsic and intrinsic factors, leading to several signs such as wrinkles, spots, and a decline in elasticity, causing a range of issues similar to those seen elsewhere in the body. Some of these factors include ultraviolet (UV) radiation, hormonal disorders, genetic factors, loss of moisture, metabolic disorders, exposure to chemicals, and smoking. Colostrum, which is the initial foremilk, has shown positive effects on the consequences of these factors. Its content is richer than mature milk and contains several beneficial components. For instance, it includes hyaluronic acid, a molecule that binds water and keeps the skin hydrated; lactoferrin, with high antimicrobial properties; immunoglobulins, which are responsible for immunity; growth factors, which increase the amount of collagen, the main protein type of the skin; and, finally, the telomerase enzyme, which maintains the telomere's length and, thus, decelerates the aging process. It has recently become apparent that using skin products with natural ingredients is essential. Considering its nature, contents, and effects, colostrum stands out as an excellent material for the cosmetic industry, especially for the aging sector. Therefore, the aim of this review article is to demonstrate the potential application of natural colostrum in skin health and its usage in natural cosmetic products in the cosmetic sector.
