Phagocytic Cell Dysfunction

Phagocytic cell dysfunction occurs when the immune cells responsible for engulfing and destroying harmful microbes or debris — such as bacteria, viruses, and dead cells — do not work properly. This can be due to genetic conditions or acquired issues, leading to increased susceptibility to infections. When these cells are impaired, the body's first line of defense fails, allowing pathogens to multiply and cause illness. Restoring their function or managing the underlying cause is essential for improving immune response and preventing recurrent infections.
