The right time to start the scanning is in the late portal venous phase, i.e. Having a liver hemangioma doesn't mean you can't become pregnant. Old scans are also extremely helpful to assess for change. [5][6], The inducible T-cell co-stimulator (CD278 or ICOS) is proven to provide a particularly critical signal for TFH cells since experimental mice deficient in ICOS are unable to develop any TFH. Those TFH cells specifically residing within a mature germinal center are sometimes referred to as GC TFH cells (for Germinal Center TFH cells) to distinguish them from pre-TFH cells.

The size of the liver lesion is an important consideration in guiding the evaluation: Lesions smaller than approximately 1.0 cm are commonly benign incidental findings on imaging studies, and in most cases represent small cysts, hemangiomas, or biliary hamartomas.

[14], GATA-3 in TH9 cells development represses transcriptional factor FOXP3, which would other wise let to other T helper cell subpopulation. The best way for a diagnosis is a biopsy or resection. Follicular helper T cells (also known as follicular B helper T cells and abbreviated as TFH), are antigen-experienced CD4+ T cells found in the periphery within B cell follicles of secondary lymphoid organs such as lymph nodes, spleen and Peyer's patches, and are identified by their constitutive expression of the B cell follicle homing receptor CXCR5. Studies have however shown that TFH have distinct gene expression profiles, supporting the theory that TFH are a subset of CD4+ T cells distinct from Th-1, Th-2, Th-17 or Tregs.
