Inflammation:  Inflammation associated with lung adenocarcinoma by   activating γδ T cells that reside in the lungs. Symbiotic   bacteria stimulate myD88-dependent IL-1B and IL-23   production in bone marrow cells, induce proliferation and   activation of Vg6 + Vd1 + γδ T cells, mediate inflammation   by inducing production of effector molecules such as   IL-17, and lead to tumor cell proliferation in LC. Here, IL17A is linked to neoplasm.
