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.

PI3Kγδ Inhibitor plus Radiation Enhances the Antitumor Immune Effect of PD-1 Blockade in Syngenic Murine Breast Cancer and Humanized Patient-Derived Xenograft Model

Murine breast cancer cells were grown in both immune-competent and -deficient BALB/c mice, and tumors were irradiated by three fractions of 24 Gy. A PD-1 blockade and a phosphoinositide 3-kinase (PI3K)γδ inhibitor were then administered every other day for two weeks.

Environmental Eustress Modulates β-ARs/CCL2 Axis to Induce Anti-tumor Immunity and Sensitize Immunotherapy against Liver Cancer in Mice

The authors demonstrated that mice living in an enriched environment were protected from carcinogen-induced liver neoplasia and transplantable syngeneic liver tumors, owning to a CD8+ T cell-dependent tumor control.

Lycopus lucidus Turcz Ameliorates DNCB-Induced Atopic Dermatitis in BALB/C Mice

The authors determined whether Lycopus lucidus Turcz (LLT) could improve 2,4‑dinitrochlorobenzene‑induced dermatitis and to verify the inhibitory effect of LLT on the expression of chemokines and pro‑inflammatory cytokines in the HaCaT immortalized keratinocyte cell line.

Regulation of the Immune Tolerance System Determines the Susceptibility to HLA-Mediated Abacavir-Induced Skin Toxicity

The authors showed the importance of immune tolerance for idiosyncratic drug toxicity (IDT) onset and determine whether it was susceptible to a common IDT, HLA-B*57:01-mediated abacavir-induced hypersensitivity, using CD4+ T cell-depleted programmed death-1 receptor-deficient HLA-B*57:01 transgenic mice

KIR3DS1 Directs NK Cell-Mediated Protection against Human Adenovirus Infections

To decipher immune recognition of human adenoviruse (HAdV) infection and determine new targets for immune-mediated control, researchers used an HAdV infection 3D organoid system, based on primary human intestinal epithelial cells.

CD8+ T Effector and Immune Checkpoint Signatures Predict Prognosis and Responsiveness to Immunotherapy in Bladder Cancer

348 pretreated metastatic urothelial cancer samples from the IMvigor210 cohort were used to identify important genes significantly associated with CD8+ T effector and immune checkpoint signatures.
