Special Issue Information

Dear Colleagues,

In the current healthcare panorama, lymphology is increasingly establishing itself as a discipline with numerous applications in every field of medicine; despite this, even today, with the continuous progress of science, it remains the prerogative of only a few specialists to the detriment of thousands of patients who suffer and often wait years before receiving a diagnosis and starting therapy.

This Special Issue of the International Journal of Molecular Sciences will focus on underlining the importance of the lymphatic system and its related diseases in all of its molecular declinations and clinical implications, and how these impact daily healthcare activities.

It is therefore hoped that this idea will push researchers and doctors who deal with this discipline to share their experiences and shed light on the countless twists and turns of a multidimensional labyrinth such as lymphology.

Since IJMS is a journal of molecular science, pure clinical studies will not suitable for our journal; however, clinical or pure model submissions with biomolecular experiments are welcomed. 

Dr. Laura Patton
Guest Editor

Drug therapy for secondary lymphedema has not yet been established. Conventional oral and intravenous administration is difficult to administer in sufficient doses due to adverse events. Therefore, it is necessary to develop a transdermal delivery system that can deliver high concentrations of drugs to the edema area. In this study, we examined the efficacy of transdermal drug delivery in a mouse model of tail edema using ultrasound irradiation (sonication method). Ultrasound irradiation can deliver high-molecular-weight substances subcutaneously, and the percutaneous administration of clobetasol propionate to the mouse tail edema model prevented the enlargement of lymphatic vessels with reduced tail volume. Therefore, steroid administration utilizing ultrasound irradiation is effective in decreasing tail swelling in a mouse tail edema model. Thus, ultrasound irradiation could have the potential to innovate the treatment of secondary lymphedema by directly administering the drug to the edema. Full article

A Comprehensive Investigation of Stimulatory Agents on MAIT and Vα7.2+/CD161− T Cell Response and Effects of Immunomodulatory Drugs

Mucosal-associated invariant T (MAIT) cells, a subset of Vα7.2+ T cells, are a crucial link between innate and adaptive immunity, responding to various stimuli through TCR-dependent and independent pathways. We investigated the responses of MAIT cells and Vα7.2+/CD161− T cells to different stimuli and evaluated the effects of Cyclosporin A (CsA) and Vitamin D3 (VitD). Peripheral blood mononuclear cells (PBMCs) from healthy donors were stimulated with various agents (PMA/Ionomycin, 5-OP-RU, 5-OP-RU/IL-12/IL-33) with or without CsA and VitD. Flow cytometric analysis assessed surface markers and intracellular cytokine production. Under steady-state conditions, MAIT cells displayed elevated expression of CCR6 and IL-13. They showed upregulated activation and exhaustion markers after activation, producing IFNγ, TNFα, and TNFα/GzB. CsA significantly inhibited MAIT cell activation and cytokine production. Conversely, Vα7.2+/CD161− T cells exhibited distinct responses, showing negligible responses to 5-OP-RU ligand but increased cytokine production upon PMA stimulation. Our study underscores the distinct nature of MAIT cells compared to Vα7.2+/CD161− T cells, which resemble conventional T cells. CsA emerges as a potent immunosuppressive agent, inhibiting proinflammatory cytokine production in MAIT cells. At the same time, VitD supports MAIT cell activation and IL-13 production, shedding light on potential therapeutic avenues for immune modulation. Full article

For many years, the significance of cardiac lymphatic vessels was largely overlooked in clinical practice, with little consideration given to their role in the pathophysiology or treatment of cardiac diseases. However, recent research has brought renewed attention to these vessels, progressively illuminating their function and importance within the realm of cardiovascular science. Experimental studies, particularly those utilizing animal models of cardiac disease, have demonstrated a clear relationship between cardiac lymphatic vessels and both the pathogenesis and progression of these conditions. These findings have prompted a growing interest in potential therapeutic applications that specifically target the cardiac lymphatic system. Conversely, while clinical investigations into cardiac lymphatics remain limited, recent studies have begun to explore their identification through specific surface markers, as well as the expression dynamics of lymphangiogenic factors. These studies have increasingly highlighted associations of lymphatic dysfunction with inflammation and fibrosis, both of which negatively impact cardiac function and remodeling across various pathological states. Despite these advances, comprehensive reviews of the current knowledge regarding the cardiac lymphatic vasculature, particularly within specific disease contexts, remain scarce. This review aims to address this gap by providing a detailed synthesis of existing reports, encompassing both animal model research and studies on human clinical specimens, with a special focus on the role of cardiac lymphatic vessels in different disease states.
