Background

CD289, also known as Toll-like receptor 9 (TLR9), is a ~115-120 kDa intracellular pattern-recognition receptor of the Toll-like receptor family that is preferentially expressed in immune-cell-rich tissues such as spleen, lymph node, bone marrow, and peripheral blood leukocytes; it senses unmethylated CpG dinucleotides in bacterial DNA and, upon activation via the adaptor protein MyD88, triggers NF-κB signaling and subsequent production of inflammatory cytokines, thereby orchestrating a T-helper-1-like innate immune response, as evidenced by impaired splenocyte proliferation, macrophage cytokine release, and dendritic-cell maturation in TLR9-deficient mice.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.
