    LAG-3 in (auto)immunity and cancer - Emphasising its role in antigen presenting cells. (PubMed, Autoimmun Rev)
    So far, studies show that both approaches may be safe and effective anti-cancer treatment options. This review summarises the role of LAG-3 in immune response and emphasises the role of this IC molecule and its soluble form on APCs function, while also noting the primary physiological function of LAG-3 in autoimmunity and providing a dual perspective of the pros and cons of this novel anti-cancer therapy.

    A phase III placebo-controlled study of eftilagimod alfa plus pembrolizumab and chemotherapy in metastatic non-small cell lung cancer. (PubMed, Future Oncol)
    TACTI-004 will evaluate whether efti can mitigate resistance to ICIs when added to SoC in NSCLC, irrespective of PD-L1 tumor status. www.clinicaltrials.gov identifier is NCT06726265.

    The inhibitory receptor Siglec-E controls antigen-presenting cell activation and T cell-mediated transplant rejection. (PubMed, Sci Transl Med)
    The human homologs Siglecs-7 and -9 were up-regulated in rejecting allograft biopsies, and their higher expression correlated with improved allograft survival. Thus, SigE/7/9 is a crucial inhibitory receptor controlling antigen-presenting cell activation and T cell-mediated transplant rejection, offering therapeutic potential.
