WebJan 22, 2024 · The expression of RHOA G17V in the T-cell lineage was recently shown to result in ICOS overexpression in a mouse model. 38 Our observation reinforces the relationship between ICOS, which may be a critical player in the oncogenesis of AITL, and the RHOA mutation. WebA diagnosis of AITL and other nodal lymphomas of T follicular helper (TFH) cell origin requires the abnormal cell population to stain positive for at least 2 and, ideally, 3 markers associated with T follicular helper cells [6]. Widely used TFH markers include ICOS, CD10, BCL6, PD1 and CXCL13.
