“Insufficient pantethine levels may be the crucial contributor to hyperactivation of dendritic cells, and autoimmune inflammation following the up-regulation of Vanins,” said study co-lead author Dr. Wei-Na Zhang. Researchers in China have found that pantethine, a derivative of vitamin B5, can alleviate symptoms of psoriasis in humans and entirely prevent the condition’s development in mice.
Pantethine suppresses dendritic cell hyperactivation
The study, published in the Journal of Experimental Medicine (JEM), identifies a metabolic pathway involving the “Vanin-pantethine-cholestrol axis.” Researchers at the State Key Laboratory of Biomedical Analysis found that Vanin enzymes are elevated in the dendritic cells of patients with psoriasis and other autoimmune diseases. The team determined that increased Vanin activity in dendritic cells reduces pantethine levels.
This deficiency triggers increased cholesterol synthesis within the dendritic cells. According to the researchers, cholesterol promotes the activation of these specialized immune cells, which then recruit other immune cells and secrete signaling molecules that drive inflammation. By replenishing pantethine levels, the researchers reversed this process, lowering cholesterol accumulation and suppressing the hyperactivation of dendritic cells.
Did you know? Psoriasis is an autoimmune condition with no known cure that causes itchy, scaly patches typically on the elbows, knees, trunk, and scalp. High blood cholesterol is cited by the researchers as a major risk factor for the disease’s development.
Clinical trial shows improvement for high-cholesterol patients
To test the theory in humans, the team conducted a small “proof-of-concept” trial involving 24 psoriasis patients. All participants were treated with a topical ointment, but half were given additional pantethine tablets. Over a 12-week period, those receiving the supplement showed improved symptoms, a result the researchers described as having “encouraging therapeutic efficacy.”
The data indicated that the benefits were most pronounced in patients who entered the trial with elevated blood cholesterol levels. While the human trial was small, the team observed that a drug inhibiting Vanins entirely prevented psoriasis in mice.
Comparing research findings across reports
Some reports focused on the broader implication that metabolic pathways are an underexplored strategy for treating inflammatory diseases.
| Subject | Observation in Mice | Observation in Humans |
|---|---|---|
| Pantethine Effect | Entirely prevented development | Alleviated symptoms (adjunctive therapy) |
| Key Driver | Vanin inhibition | Linked to blood cholesterol levels |
Future applications for autoimmune diseases
Dr. Zhang stated that these findings provide a foundation for treating other dendritic cell-mediated autoimmune diseases. The researchers argue that because dendritic cells coordinate various parts of the immune system by presenting antigens to T-cells, targeting their metabolism could offer a new class of therapeutic strategies for a range of inflammatory conditions.
Pro Tip: Pantethine is a nutritional supplement.
Pantethine alleviates psoriasis symptoms by limiting dendritic cells
Can pantethine cure psoriasis?
No. The researchers describe pantethine as an “adjunctive therapy” that helps alleviate symptoms rather than a cure, as psoriasis currently has no known cure.
Who benefits most from this supplement?
The clinical trial showed that patients with elevated blood cholesterol levels showed the most significant improvement in symptoms during the 12-week study.
How does pantethine affect the immune system?
It limits the activity of dendritic cells by lowering cholesterol synthesis, which prevents these cells from hyperactivating and triggering the inflammation associated with autoimmune responses.
The researchers noted that these findings should be interpreted as proof-of-concept for clinical feasibility rather than direct mechanistic validation.
