    Abstract

    CD127+ CD94+ Innate Lymphoid Cells Expressing Granulysin and Perforin Are Expanded in Patients with Crohn’s Disease

    The authors analyzed CD127+ innate lymphoid cells (ILCs) and natural killer cells in intestinal lamina propria from healthy donors and Crohn’s disease patients and identified two populations of CD127+CD94+ ILCs, designated population A and B, that could be distinguished on the expression of CD117, CD18 and cytotoxic molecules.

    Abstract

    Activation of Toll-Like Receptor 2 Enhances Peripheral and Tumor-Infiltrating CD8+ T Cell Cytotoxicity in Patients with Gastric Cancer

    Expression profile of TLRs in peripheral and tumor-infiltrating CD8+ T cells was investigated. Purified CD8+ T cells were stimulated with Pam3Csk4, an agonist of TLR2, and cytotoxic and co-inhibitory molecules in CD8+ T cells was measured.

    Abstract

    The Fellowship of Regulatory and Tissue-Resident Memory Cells

    T cells located in non-lymphoid tissues have come to prominence in recent years. CD8+ tissue-resident memory cells are important for tissue immune surveillance, provide an important line of defence against invading pathogens and show promise in cancer therapies.
