Abstract: The present invention relates to a combination use of a novel Lactobacillus plantarum IMB19 strain and/or polysaccharides derived from the strain with an anticancer drug for preventing or treating tumors. The novel Lactobacillus plantarum IMB19 strain and polysaccharides derived from the strain of the present invention exhibit an excellent ability to stimulate CD8+T cell activity and exhibit excellent Treg cell inhibitory activity, and stimulate and improve antitumor immune response through various mechanisms such as increased macrophage infiltration in CPS tumors and differentiation and reprogramming of macrophages into an inflammatory phenotype (M1). Furthermore, the strain and the polysaccharides may significantly increase antitumor immune response when administered in combination with an anticancer drug, particularly an immuno-anticancer drug such as a PD-1 or PD-L1 inhibitor (e.g.

Abstract: The present invention relates to a novel Lactobacillus plantarum IMB19 strain, polysaccharides derived from the strain, and a use thereof. A novel Lactobacillus plantarum IMB19 strain and polysaccharides derived from the strain of the present invention exhibit an excellent CD8+T cell activity stimulating ability and Treg cell inhibitory activity, and stimulate and improve an antitumor immune response through various mechanisms such as increased macrophage infiltration in CPS tumors and differentiation and reprogramming of macrophages into an inflammatory phenotype (M1). Therefore, a strain and polysaccharides derived from the strain of the present invention can be effectively used for immune regulation, especially immune boosting, in a subject, and can inhibit tumor growth by inducing and enhancing an antitumor immune response.
