Macrophages: These cells become activated and produce pro-inflammatory cytokines that help in amplifying the immune response.
Natural Killer Cells: They directly attack tumor cells, promoting apoptosis, or programmed cell death, which is crucial for eliminating malignant cells.
T-Lymphocytes: Specifically, CD4+ and CD8+ T-cells become mobilized, circulating to enhance tumor cell recognition and destruction.

In addition, BCG triggers the secretion of various cytokines that are essential for cell signaling in immune processes. This elevated immune surveillance often results in a significant reduction in tumor recurrence rates among patients treated with BCG. Thus, healthy bladder tissue is protected while actively targeting tumor cells.

Direct Effects on Tumor Cells

BCG not only boosts the immune system but also directly affects tumor cells. Studies have shown that BCG can induce apoptosis in bladder cancer cells upon administration. BCG adheres to the surface of these cells, which leads to the following:

Cellular communication disruption: The bacterial components can interfere with cell signaling pathways within bladder tumor cells, effectively inhibiting their growth.
Upregulation of death receptors: This process enhances the tumor cells’ sensitivity to immune-mediated destruction, making them more susceptible to attack by the immune system.
Cytokine Release: The combination of immune cell activation and cytokine release creates a hostile environment for tumor growth. Tumor cells become unable to thrive as their supportive structures break down, leading to further inhibition of their proliferation.

"Through immune enhancement and direct antitumor effects, BCG exemplifies a unique approach to bladder cancer treatment that requires nuanced understanding of its mechanisms."

The combined action of BCG's immunogenic properties and its targeted effects on tumor cells demonstrate why this treatment is a pivotal option for those suffering from bladder cancer. The implications of these mechanisms extend beyond mere efficacy, reminding healthcare professionals to remain cognizant of both therapeutic benefits and potential risks associated with BCG therapy.
