Derms and Conditions Podcast Episode 80:

The OX40/OX40L Pathway: Expanding Our Understanding of Atopic Dermatitis

Featuring Shawn Kwatra, MD | Release Date: May 23, 2024

In this episode of Derms and Conditions, host James Q Del Rosso, DO, is joined by Shawn Kwatra, MD, to discuss an intriguing breakthrough in atopic dermatitis (AD) therapeutics: the OX40/OX40 ligand pathway. As advancements in AD treatment continue to unfold rapidly, this pathway has emerged as a novel target, presenting a promising avenue for achieving long-term relief by targeting upstream inflammatory signals. By normalizing disease processes and potentially inducing longer periods of remission, understanding this pathway may offer a paradigm shift in AD management.

They begin with an overview of the OX40/OX40 ligand pathway, a key regulatory mechanism believed to govern type 2 inflammation at its source. The OX40/OX40 ligand serves as a crucial costimulatory molecule, facilitating communication between immune cells. This interaction, occurring upstream in the inflammatory cascade, has become the focus of therapeutic interventions aimed at modulating AD.

They also highlight the impact of the heterogeneity of AD, characterized by various cytokine profiles and immune responses, emphasizing the significance of targeting the OX40/OX40 ligand pathway. By intervening at this early stage, it becomes possible to personalize treatment strategies and address the diverse manifestations of the disease.

They then discuss the potential of OX40/OX40 ligand modulation to influence immune memory, leading to sustained responses even after treatment cessation. Clinical data suggest the possibility of extended remission periods, enabling a shift towards disease modification rather than symptom control alone.

Looking ahead, the pair discusses how the integration of OX40/OX40 ligand-targeted therapies with existing treatments could yield synergistic effects, expanding treatment options for not only AD but also related inflammatory conditions.

Tune in to the full episode to learn more about this novel target and how it may revolutionize the management of a spectrum of immune-mediated diseases.
