Abstract:
Sezary Syndrome is an aggressive T-cell Lymphoma involving blood, skin and lymphonodes Involvement of the CXCR4-SDF1 has been previously shown. We here present evidence also of the involvement of B-arrestin a downstream regulator of CXCR4, that is depleted and downregulated as well as a potential functional role for this depletion.
Insights
Sezary Syndrome, an aggressive T-cell lymphoma, involves the CXCR4-SDF1 pathway. This study reveals B-arrestin depletion and downregulation, suggesting its functional role in the disease progression.
Area of Science:
- Oncology
- Immunology
- Cell Biology
Background:
- Sezary Syndrome is an aggressive cutaneous T-cell lymphoma affecting blood, skin, and lymph nodes.
- The CXCR4-SDF1 signaling axis is implicated in the pathogenesis of Sezary Syndrome.
