CEACAM1 structure and function in immunity and its therapeutic implications.

ABSTRACT: The type I membrane protein receptor carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) distinctively exhibits significant alternative splicing that allows for tunable functions upon homophilic binding. CEACAM1 is highly expressed in the tumor environment and is strictly regulated on lymphocytes such that its expression is restricted to activated cells where it is now recognized to function in tolerance pathways. CEACAM1 is also an important target for microbes which have co-opted these attributes of CEACAM1 for the purposes of invading the host and evading the immune system. These properties, among others, have focused attention on CEACAM1 as a unique target for immunotherapy in autoimmunity and cancer. This review examines recent structural information derived from the characterization of CEACAM1:CEACAM1 interactions and heterophilic modes of binding especially to microbes and how this relates to CEACAM1 function. Through this, we aim to provide insights into targeting CEACAM1 for therapeutic intervention.

Project description:Uncontrolled activation of the Hedgehog/Glioma-associated oncogene (HH/GLI) pathway is a potent oncogenic driver signal promoting numerous cancer hallmarks such as proliferation, survival, angiogenesis, metastasis and metabolic rewiring. Several HH pathway inhibitors have already been approved for medical therapy of advanced and metastatic basal cell carcinoma and acute myeloid leukemia with partially impressive therapeutic activity. However, de novo and acquired resistance as well as severe side effects and unexplained lack of therapeutic efficacy are major challenges that urgently call for improved treatment options with more durable responses. The recent breakthroughs in cancer immunotherapy have changed our current understanding of targeted therapy and opened up promising therapeutic opportunities including combinations of selective cancer pathway and immune checkpoint inhibitors. Although HH/GLI signaling has been intensely studied with respect to the classical hallmarks of cancer, its role in the modulation of the anti-tumoral immune response has only become evident in recent studies. These have uncovered HH/GLI regulated immunosuppressive mechanisms such as enhanced regulatory T-cell formation and production of immunosuppressive cytokines. In light of these exciting novel data on oncogenic HH/GLI signaling in immune cross-talk and modulation, we summarize and connect in this review the existing knowledge from different HH-related cancers and chronic inflammatory diseases. This is to provide a basis for the investigation and evaluation of novel treatments combining immunotherapeutic strategies with approved as well as next-generation HH/GLI inhibitors. Further, we also critically discuss recent studies demonstrating a possible negative impact of current HH/GLI pathway inhibitors on the anti-tumoral immune response, which may explain some of the disappointing results of several oncological trials with anti-HH drugs.

Project description:The mechanistic target of rapamycin (mTOR) pathway integrates metabolic cues into cell fate decisions. A particularly fateful event during the adaptive immune response is the engagement of a T cell receptor by its cognate antigen presented by an antigen-presenting cell (APC). Here, the induction of adequate T cell activation and lineage specification is critical to mount protective immunity; at the same time, inadequate activation, which could lead to autoimmunity, must be avoided. mTOR forms highly conserved protein complexes 1 and 2 that shape lineage specification by integrating signals originating from TCR engagement, co-stimulatory or co-inhibitory receptors and cytokines and availability of nutrients. If one considers autoimmunity as the result of aberrant lineage specification in response to such signals, the importance of this pathway becomes evident; this provides the conceptual basis for mTOR inhibition in the treatment of systemic autoimmunity, such as systemic lupus erythematosus (SLE). Clinical trials in SLE patients have provided preliminary evidence that mTOR blockade by sirolimus (rapamycin) can reverse pro-inflammatory lineage skewing, including the expansion of Th17 and double-negative T cells and plasma cells and the contraction of regulatory T cells. Moreover, sirolimus has shown promising efficacy in the treatment of refractory idiopathic multicentric Castleman disease, newly characterized by systemic autoimmunity due to mTOR overactivation. Alternatively, mTOR blockade enhances responsiveness to vaccination and reduces infections by influenza virus in healthy elderly subjects. Such seemingly contradictory findings highlight the importance to further evaluate the clinical effects of mTOR manipulation, including its potential role in treatment of COVID-19 infection. mTOR blockade may extend healthy lifespan by abrogating inflammation induced by viral infections and autoimmunity. This review provides a mechanistic assessment of mTOR pathway activation in lineage specification within the adaptive and innate immune systems and its role in health and autoimmunity. We then discuss some of the recent experimental and clinical discoveries implicating mTOR in viral pathogensis and aging.
