Helminthic Therapy

Helminthic Therapy is a collection of research notes, reflections, and deeper dives into the science of therapeutic helminths. These pieces highlight studies, ideas, and perspectives that go beyond what’s covered in other resources. For complete and up-to-date information, see the Helminthic Therapy Wiki, the world’s largest information database documenting the science, management, experience, and results of helminth replacement.

Immune Modulation and the Plateau Phenomenon

Immune Modulation and the Plateau Phenomenon

Helminthic therapy reliably shifts immune responses toward regulation, reducing exaggerated inflammation without broad suppression. Outcomes often vary, with some individuals achieving full remission and others stabilizing at a plateau of partial improvement. This article explores the mechanisms behind these divergent results, emphasizing system constraints, sustaining drivers of immune activation, and why plateaus signal the limits of modulation rather than failure.

Key enzymes – NA

by

Necator americanus, a human hookworm parasite, produces a variety of enzymes primarily in its excretory-secretory (ES) products and exsheathing fluids across larval and adult stages. These enzymes aid in host invasion, nutrient acquisition (such as blood feeding), tissue migration, and immune modulation. Many are proteases that facilitate penetration and digestion while also influencing host inflammatory … Read more

Secretome of Necator americanus

by

The broader secretome of Necator americanus, the human hookworm, encompasses the full array of excretory-secretory (ES) products released by larval and adult stages to facilitate infection, survival, and host modulation. This includes not only the enzymes discussed previously (e.g., proteases for tissue penetration and nutrient digestion) but also a diverse set of non-enzymatic proteins, antioxidants, … Read more

How Helminths Help Despite Elevated IL-10 in Multiple Sclerosis (MS)

by

High IL-10 is not the same as healthy IL-10. Helminths restore immune regulation in multiple sclerosis by expanding functional IL-10–producing regulatory B cells and activating complementary anti-inflammatory pathways. This coordinated network restrains pathogenic Th1/Th17 responses, enhances neuroprotection, and rebalances IL-10 signaling in MS.

Why Some People Respond to Helminthic Therapy and Others Do Not

by

Helminthic therapy shows about a 75% response rate, but outcomes vary widely. Success depends on condition type, immune baseline, genetics, microbiome, dose, and consistency. Every immune system is unique, so not all patients respond the same way.
