What is the fine-grained topic of the following text: Two independent studies published in the March issue of Journal of Experimental Medicine (1,2) show that thymic stromal lymphopoietin (TSLP), an IL-7-related cytokine abundant in the tumor microenvironment, instructs dendritic cells (DCs) to shift the balance toward Th2-mediated inflammatory responses that incite and sustain tumor progression. Only return the topic.
The role of thymic stromal lymphopoietin (TSLP) in tumor progression.
