Synergistic action of lactoferrin in enhancing the safety and effectiveness of docetaxel treatment against prostate cancer.

Background: Tumor metastasis is promoted by an immunosuppressive environment. Lactoferrin (Lf) is known to regulate immunological activity in tumor cells and inhibit processes associated with tumor metastasis. A delivery of lactoferrin with docetaxel (DTX) in prostate cancer cells in the form of DTX-loaded lactoferrin nanoparticles (DTX-LfNPs) would provide a dual activity wherein the lactoferrin affects metastasis and DTX chemotherapeutically inhibits mitosis and cell division.

Sulfonate modified Lactoferrin nanoparticles as drug carriers with dual activity against HIV-1.

Intriguing properties and structural dynamics of Lactoferrin have been exploited in numerous applications, including its use as self-assembling, pH sensitive nanoparticles to deliver intended cargo at the disease site. In this study, we explore the possibility of surface modification of Lactoferrin nanoparticles to hone its specificity to target HIV-1 infected cells. Existence of free cysteine groups on Lactoferrin nanoparticles available for reaction with external molecules facilitates conjugation on the surface with Sodium 2-mercaptoethanesulfonate (MES).
