Intradermal versus subcutaneous immunization: Effects of administration route using a lipid-PLGA hybrid nanoparticle tuberculosis vaccine.

Tuberculosis (TB) remains a significant global health challenge, latently affecting around a quarter of the global population. The sole licensed TB vaccine, Mycobacterium bovis Bacillus Calmette-Guérin (BCG), shows variable efficacy, particularly among adolescents and adults, underscoring the pressing need for more effective vaccination strategies. The administration route is crucial for vaccine efficacy, and administration via the skin, being rich in immune cells, may offer advantages over conventional subcutaneous routes, which lack direct access to abundant antigen-presenting cells.

A Versatile, Low-Cost Modular Microfluidic System to Prepare Poly(Lactic-co-Glycolic Acid) Nanoparticles With Encapsulated Protein.

Objective: Microfluidics has emerged as a promising technique to prepare nanoparticles. However, the current microfluidic devices are mainly chip-based and are often integrated into expensive systems that lack on-the-spot versatility. The aim of this study was to set up a modular microfluidic system based on low-cost capillaries and reusable, easy-to-clean building blocks that can prepare poly(D,L-lactic-co-glycolic acid) (PLGA) nanoparticles with and without incorporated water-soluble biomacromolecules.

Evaluation of PLGA, lipid-PLGA hybrid nanoparticles, and cationic pH-sensitive liposomes as tuberculosis vaccine delivery systems in a Mycobacterium tuberculosis challenge mouse model - A comparison.

Tuberculosis (TB) continues to pose a global threat for millennia, currently affecting over 2 billion people and causing 10.6 million new cases and 1.3 million deaths annually.

Lesional Psoriasis is Associated With Alterations in the Stratum Corneum Ceramide Profile and Concomitant Decreases in Barrier Function.

Psoriasis is an inflammatory skin disease associated with an impaired skin barrier. The skin barrier function is dependent on the extracellular lipid matrix which surrounds the corneocytes in the stratum corneum. Ceramides comprise essential components of this matrix.
