Web13 Apr 2024 · Many pathogens rarely cause invasive diseases during neonatal life. Bee et al. delineate an immunologic determinant of this phenomenon. During early life, developmental impairments in macrophage function (efferocytosis) alter neutrophil homeostasis to augment CD11b-dependent opsonophagocytosis. This results in increased protection … Web(A) Direct CTL-mediated killing requires cell–cell contact and commonly results from the release of cytolytic enzymes such as granzyme B. Perforin, released by the CTL, forms pores in the membrane of a juxtaposed target cell allowing passive inward diffusion of granzyme B, which then triggers apoptosis of the targeted cell.
