Inflammatory Modulation Effects of Probiotics: A Safe and Promising Modulator for Cancer Prevention

Chronic inflammation is the gate of many human illnesses and happens when the immune system is unable to suppress external attacks in the correct form. Nonetheless, the gut microbiome plays a pivotal role in keeping homeostasis in the human body and preventing inflammation. Imbalanced microbiota and many diseases can result in inflammation, which when not taken seriously, can be turned into chronic ones and ultimately lead to serious diseases such as cancer. One approach to maintaining hemostasis in the human body is consumption of probiotics as a supplement. Probiotics impact the immune functions of dendritic cells (DCs), T cells, and B cells in the gut-associated lymphoid tissue by inducing the secretion of an array of cytokines. They activate the innate immune response through their microbial-associated molecular pattern, and this activation is followed by multiple cytokine secretion and adaptive elicitation that mitigates pro-inflammatory expression levels and tumor incidence. Thus, according to several studies showing the benefit of probiotics application, alone or in combination with other agents, to induce potent immune responses in individuals against some inflammatory disorders and distinct types of cancers, this review is devoted to surveying the role of probiotics and the modulation of inflammation in some cancer models.
