These cellular alterations translate into physiological decline: PAI-1 drives cardiovascular aging by promoting vascular senescence and arterial stiffening, contributes to cognitive decline by impairing amyloid-beta clearance, fuels cancer progression through angiogenesis and immune suppression, and exacerbates muscle atrophy by hindering regeneration. A rare loss-of-function SERPINE1 mutation extends lifespan, illustrating how lifelong PAI-1 reduction can positively impact the human healthspan.

Local inflammation in tumor environment after PDT can be effective in eliciting an immune response to improve treatment efficiency but it causes some early and long-term side effects in local and surround tissues, resulting leads to incidental effects and unwilling consequences such as pain, erythema and infection. Moreover, the mechanism of inflammation in PDT is not clear. Employment of non-optimized protocol including cytotoxic photosensitizer (PS) and fluence and fluence rate during PDT can bring biased outcomes for patients in terms of inflammation and treatment. In PDT, the minimum cytotoxicity and side effects of normal tissue depend on several factors, including the type and location of the tumor to be treated, the PS used, laser power, oxygen level, tumor properties and the patient's individual characteristics.
