TG6, Lymphocyte Patterns and Early Autoimmunity

What if some of the immune activity we’re looking for isn’t showing up where we expect to find it?

In this episode, I sit down with Robyn Puglia of Cyrex Laboratories to explore TG6, lymphocyte patterns, and early autoimmunity—and specialized testing many practitioners may not realize is available through Cyrex Wheat Burden panel, the Lymphocyte Map, and Array 5.

We look at neurological manifestations of gluten-related disease, what different immune cell populations may add to the clinical picture, and how autoantibodies can sometimes appear before autoimmune disease is diagnosed.

The bigger question: Can seeing more of the immune story help us ask better questions about what may be driving a complex presentation?

• Why gluten reactivity isn’t always a gut story. TG6 has been studied in gluten-related neurological disorders, particularly gluten ataxia. (Hadjivassiliou 2019) We discuss why neurological symptoms may belong in the gluten conversation and what Cyrex Wheat Burden Panel is designed to investigate beyond conventional celiac markers. (Mearns 2019)
• What your lymphocyte count may not tell you. T cells, B cells, natural killer cells, and their subsets have different jobs. Robyn explains how the Cyrex Lymphocyte Map looks at these populations and how patterns may help practitioners decide what to investigate next.
• Why autoimmunity may start before the diagnosis. Disease-associated autoantibodies can precede clinical disease in several autoimmune conditions. (Ma 2017) We explore Cyrex Array 5, tissue-associated autoantibodies, and what these earlier immune signals may—and may not—tell us. (Frazzei 2022)

Robyn Puglia’s work with celiac disease, neurological symptoms, autoimmunity, and complex chronic illness pushed her to ask what the immune system might be telling us beyond a routine workup. Today, as Vice President of Practitioner Education at Cyrex L
