TNF and glaucoma: Since elevated levels of TNF‐α in the AH and loss of TM cells are common characteristics of glaucoma,10, 14 and hypoxia was observed to robustly upregulate expression of vasorin in TM cells, we evaluated the effects of vasorin on TNF‐α induced cell death and found that vasorin suppresses TNF‐α induced cell death in TM cells.
