Abstract
The pathogenesis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection involves dysregulations of iron metabolism, and although the mechanism of this pathology is not yet fully understood, correction of iron metabolism pathways seems a promising pharmacological target. The previously observed effect of inhibiting SARS-CoV-2 infection by ferristatin II, an inducer of transferrin receptor 1 (TfR1) degradation, prompted the study of competition between Spike protein and TfR1 ligands, especially lactoferrin (Lf) and transferrin (Tf). We hypothesized molecular mimicry of Spike protein as cross-reactivity of Spike-specific antibodies with Tf and Lf. Thus, strong positive correlations (R2 > 0.95) were found between the level of Spike-specific IgG antibodies present in serum samples of COVID-19-recovered and Sputnik V-vaccinated individuals and their Tf-binding activity assayed with peroxidase-labeled anti-Tf. In addition, we observed cross-reactivity of Lf-specific murine monoclonal antibody (mAb) towards the SARS-CoV-2 Spike protein. On the other hand, the interaction of mAbs produced to the receptor-binding domain (RBD) of the Spike protein with recombinant RBD protein was disrupted by Tf, Lf, soluble TfR1, anti-TfR1 aptamer, as well as by peptides RGD and GHAIYPRH. Furthermore, direct interaction of RBD protein with Lf, but not Tf, was observed, with affinity of binding estimated by KD to be 23 nM and 16 nM for apo-Lf and holo-Lf, respectively. Treatment of Vero E6 cells with apo-Lf and holo-Lf (1–4 mg/mL) significantly inhibited SARS-CoV-2 replication of both Wuhan and Delta lineages. Protective effects of Lf on different arms of SARS-CoV-2-induced pathogenesis and possible consequences of cross-reactivity of Spike-specific antibodies are discussed.

Lactotransferrin gene functional polymorphisms do not influence susceptibility to human immunodeficiency virus-1 mother-to-child transmission in different ethnic groups. Mem Inst Oswaldo Cruz 2015; 110:222-9. [PMID: 25946246 PMCID: PMC4489453 DOI: 10.1590/0074-02760140447] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2014] [Accepted: 03/05/2015] [Indexed: 11/29/2022] Open
Abstract
Lactotransferrin, also known as lactoferrin, is an iron binding glycoprotein that
displays antiviral activity against many different infectious agents, including human
immunodeficiency virus (HIV)-1. Lactotransferrin is present in the breast milk and in
the female genitourinary mucosa and it has been hypothesised as a possible candidate
to prevent mother-to-child HIV-1 transmission. To verify if two functional
polymorphisms, Thr29Ala and Arg47Lys, in the lactotransferrin encoding gene (LTF)
could affect HIV-1 infection and vertical transmission, a preliminary association
study was performed in 238 HIV-1 positive and 99 HIV-1 negative children from Brazil,
Italy, Africa and India. No statistically significant association for the Thr29Ala
and Arg47Lys LTF polymorphisms and HIV-1 susceptibility in the studied populations
was found. Additionally LTF polymorphisms frequencies were compared between the four
different ethnic groups.
