'We then found an older study, from 2004, which showed that the fusion between phagosomes and lysosomes is blocked by these two enzymes.
In macrophages, the infectious agent is degraded within the phagosomes, and components of the pathogen are presented to the cells involved in the adaptive immune response [17].

Autophagy may be involved in the removal of pathogens that enter the cytoplasm through the cell membrane or through phagosomes, suggesting that a bacterial infection may activate autophagy [17].

In addition, they performed Western blot and confocal microscopy experiments, where it was observed that simvastatin promotes maturation in phagosomes and autophagy in macrophages infected by M.

[7] The antimicrobial peptide, Cathelicidin is directly up-regulated by 1, 25[(OH).sub.2]D [8-9] which helps in phagocytosis of Mtb followed by fusion of phagosomes with lysosomes to form autolysosomes and expression of lysosomal enzymes and reactive oxygen species.
These mineralized bodies range in diameter from 5 mm to 10 mm, look like owl eyes or ring particles and are present in intact histiocyte phagosomes. Ultrastructurally, they are composed of concentric crystalline laminations with a thick inner zone and a fine outer zone.
