← Human Body & HealthWhy does severe lymphedema increase susceptibility to skin infections?
A)Increased immune cell migration
B)Enhanced epidermal barrier function
C)Impaired antigen presentation locally✓
D)Decreased local blood perfusion
💡 Explanation
Lymphedema obstructs lymphatic drainage, which disrupts antigen presentation by antigen-presenting cells within the affected tissue. This impairment reduces the local immune response because it hinders the activation of T cells and other immune cells. Therefore, the area becomes more vulnerable to infection rather than being protected by enhanced barrier function or increased immune cell migration.
