Immunotherapy in Lung Cancer: Current Landscape and Future Directions

Frontiers in Immunology, Год журнала: 2022, Номер 13

Опубликована: Фев. 9, 2022

Over the past decade, lung cancer treatment has undergone a major paradigm shift. A greater understanding of biology led to development many effective targeted therapies as well immunotherapy. Immune checkpoint inhibitors (ICIs) have shown tremendous benefit in non-small cell (NSCLC) and are now being used first-line metastatic disease, consolidation therapy following chemoradiation unresectable locally advanced adjuvant surgical resection chemotherapy resectable disease. Despite these benefits, predicting who will respond ICIs proven be difficult there remains need discover new predictive immunotherapy biomarkers. Furthermore, resistance is frequent either because lack response or disease progression after an initial response. The utility small (SCLC) limited extensive stage combination with modest impact on overall survival. It thus important explore exploit additional targets reap full benefits cancer. Here, we summarize current state cancer, discuss novel targets, intersection between DNA repair defects

Cancer immunotherapies: advances and bottlenecks

Frontiers in Immunology, Год журнала: 2023, Номер 14

Опубликована: Авг. 24, 2023

Immunotherapy has ushered in a new era cancer treatment, and immunotherapy continues to be rejuvenated. The clinical goal of is prime host immune system provide passive or active immunity against malignant tumors. Tumor infiltrating leukocytes (TILs) play an immunomodulatory role tumor microenvironment (TME) which closely related escape cells, thus influence progress. Several immunotherapies, include checkpoint inhibitors (ICIs), vaccine, adoptive cell transfer (ACT), have shown great efficacy promise. In this review, we will summarize the recent research advances immunotherapy, including molecular mechanisms effects as well limitations immunotherapy.

Targeting LAG-3, TIM-3, and TIGIT for cancer immunotherapy

Journal of Hematology & Oncology, Год журнала: 2023, Номер 16(1)

Опубликована: Сен. 5, 2023

Abstract In one decade, immunotherapy based on immune checkpoint blockades (ICBs) has become a new pillar of cancer treatment following surgery, radiation, chemotherapy, and targeted therapies. However, not all patients benefit from single or combination therapy with anti-CTLA-4 anti-PD-1/PD-L1 monoclonal antibodies. Thus, an increasing number proteins (ICPs) have been screened their effectiveness evaluated in preclinical clinical trials. Lymphocyte activation gene-3 (LAG-3), T cell immunoglobulin mucin-domain-containing-3 (TIM-3), immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT) constitute the second wave targets that show great promise for use solid tumors leukemia. To promote research application ICBs directed at these targets, we summarize discovery, mechanism, efficiency, trial results this review.

TIGIT-CD226-PVR axis: advancing immune checkpoint blockade for cancer immunotherapy

Journal for ImmunoTherapy of Cancer, Год журнала: 2022, Номер 10(4), С. e004711 - e004711

Опубликована: Апрель 1, 2022

Recent advances in understanding the roles of immune checkpoints allowing tumors to circumvent system have led successful therapeutic strategies that fundamentally changed oncology practice. Thus far, immunotherapies against only two checkpoint targets been approved, CTLA-4 and PD-L1/PD-1. Antibody blockade these enhances function antitumor T cells at least part by relieving inhibition cell costimulatory receptor CD28. These successes stimulated considerable interest identifying other pathways may bte targeted alone or together with existing immunotherapies. One such axis is comprised members PVR/nectin family includes inhibitory immunoreceptor Ig tyrosine-based domains (TIGIT). Interestingly, TIGIT acts regulate activity a second CD226 works parallel There are currently over dozen TIGIT-directed blocking antibodies various phases clinical development, testament promise modulating this pathway enhance responses. In review, we discuss role as inhibitor, its interplay activating counter-receptor CD226, status next advance cancer immunotherapy.

Co-inhibition of TIGIT and PD-1/PD-L1 in Cancer Immunotherapy: Mechanisms and Clinical Trials

Molecular Cancer, Год журнала: 2023, Номер 22(1)

Опубликована: Июнь 8, 2023

Abstract Over the past decade, immune checkpoint inhibitors (ICIs) have emerged as a revolutionary cancer treatment modality, offering long-lasting responses and survival benefits for substantial number of patients. However, response rates to ICIs vary significantly among individuals types, with notable proportion patients exhibiting resistance or showing no response. Therefore, dual ICI combination therapy has been proposed potential strategy address these challenges. One targets is TIGIT, an inhibitory receptor associated T-cell exhaustion. TIGIT diverse immunosuppressive effects on immunity cycle, including inhibition natural killer cell effector function, suppression dendritic maturation, promotion macrophage polarization M2 phenotype, differentiation T cells regulatory cells. Furthermore, linked PD-1 expression, it can synergize PD-1/PD-L1 blockade enhance tumor rejection. Preclinical studies demonstrated co-inhibition in enhancing anti-tumor improving outcomes several types. Several clinical trials are underway evaluate safety efficacy various results awaited. This review provides overview mechanisms treatment, summarizes latest investigating this therapy, discusses its prospects. Overall, represents promising therapeutic approach that improve treated ICIs.

Exploiting innate immunity for cancer immunotherapy

Molecular Cancer, Год журнала: 2023, Номер 22(1)

Опубликована: Ноя. 27, 2023

Abstract Immunotherapies have revolutionized the treatment paradigms of various types cancers. However, most these immunomodulatory strategies focus on harnessing adaptive immunity, mainly by inhibiting immunosuppressive signaling with immune checkpoint blockade, or enhancing immunostimulatory bispecific T cell engager and chimeric antigen receptor (CAR)-T cell. Although agents already achieved great success, only a tiny percentage patients could benefit from immunotherapies. Actually, immunotherapy efficacy is determined multiple components in tumor microenvironment beyond immunity. Cells innate arm system, such as macrophages, dendritic cells, myeloid-derived suppressor neutrophils, natural killer unconventional also participate cancer evasion surveillance. Considering that cornerstone antitumor response, utilizing immunity provides potential therapeutic options for control. Up to now, exploiting agonists stimulator interferon genes, CAR-macrophage -natural therapies, metabolic regulators, novel exhibited potent activities preclinical clinical studies. Here, we summarize latest insights into roles cells discuss advances arm-targeted strategies.
