Fagolysosomes

Fagolysosomes are cellular structures formed during phagocytosis, a process by which certain cells engulf large particles. When a cell, such as a phagocyte, encounters a target particle like a bacterium or cellular debris, it extends pseudopods to surround and internalize the particle into a membrane-bound vesicle called a phagosome. The phagosome then fuses with a lysosome, an organelle containing hydrolytic enzymes. This fusion event creates the fagolysosome. Within the fagolysosome, the enzymes from the lysosome break down the engulfed material, effectively digesting it. This process is crucial for immunity, clearing pathogens, and removing cellular waste. The formation of fagolysosomes is a fundamental mechanism for cellular defense and housekeeping. The contents of the fagolysosome are degraded into smaller molecules that can be reused by the cell or expelled. This dynamic fusion and degradation process highlights the coordinated function of different cellular compartments.
