TIM-3 is one of the key immune checkpoint receptors that interact with GAL-9, PtdSer, HMGB1 and CEACAM1. Initially identified on the surface of T helper 1 (Th1) lymphocytes and later on cytotoxic lymphocytes (CTLs), monocytes, macrophages, natural killer cells (NKs), and dendritic cells (DCs), TIM-3 plays a key role in immunoregulation. Recently, a growing body of evidence has shown that its differential expression in various tumor types indicates a specific prognosis for cancer patients. Here, we discuss which types of cancer TIM-3 can serve as a prognostic factor and the influence of coexpressed immune checkpoint inhibitors, such as LAG-3, PD-1, and CTLA-4 on patients' outcomes. Currently, experimental medicine involving TIM-3 has significantly enhanced the anti-tumor effect and improved patient survival. In this work, we summarized clinical trials incorporating TIM-3 targeting monoclonaland bispecific antibodies in monotherapy and combination therapy and highlighted the emerging role of cell-based therapies.  \nKeywords Cancer · Immunotherapy · TIM-3 · T-cells  \n* Julita Kulbacka [julita.kulbacka@umw.edu.pl](julita.kulbacka@umw.edu.pl)  \n1 Faculty of Pharmacy, Wroclaw Medical University, Wroclaw, Poland  \n2 Faculty of Medicine, Wroclaw Medical University, Wroclaw, Poland  \n3 Faculty of Chemistry, Wroclaw University of Science and Technology, Wroclaw, Poland  \n4 Faculty of Medicine, Poznan University of Medical Sciences, Poznan, Poland  \n5 State Research Institute Centre for Innovative Medicine, Department of Immunology, Vilnius, Lithuania  \n6 Department of Molecular and Cellular Biology, Faculty of Pharmacy, Wroclaw Medical University, Wroclaw, Poland  \n7 Faculty of Electronics, Vilnius Gediminas Technical University, Vilnius, Lithuania  \n8 Department of Drug Technology, Faculty of Pharmacy, Wroclaw Medical University, Wroclaw, Poland  \nTIM‑3 structure and function  \nT-cell immunoglobulin and mucin domain-containing protein 3 (TIM-3) is identified as an immune checkpoint that is expressed in various kinds of immune cells and plays a key role in immunoregulation. TIM-3 belongs to the TIM family, which includes three members in humans (TIM-1, TIM-3 and TIM-4) and eight members in mice (TIM-1 to TIM-8) . Members of the TIM family are type I surface glycoproteins that share similar molecular structures containing a mucin domain, amino-terminal immunoglobulin variable domain (V domain) with five noncanonical cysteines, a transmembrane domain and a cytoplasmic tail [1, 2] .  \nThe IgV Tim-3 domain is formed of antiparallel beta sheets. A disulfide bond formed by four non-canonical cysteines binds the front and back sheets together to stabilize the IgV domain [3] . These two bonds form a unique\"cleft\" in Tim-3 and a small associated channel. The cleft formed by the CC′ and FG loops is stabilized by two noncanonical disulfide bonds, as well as a series of conserved ionic interactions and hydrogen bonds. It is a response site for ligand binding, such as phosphatidylserine. These unique  \nconformational surface features may be involved in Tim-3's biological function of ligand recognition [4] .  \nThe IgV domain is stabilized by two hydrogen bonds, which are present in almost all IgSF domains—","cbCaieAfZ7gvaNcj","https://ap.wps.com/l/cbCaieAfZ7gvaNcj","pdf",1616854,21,"English","# Abstract\n## TIM‑3 structure and function\n## TIM‑3 ligands and immune regulatory effects","[{\"question\":\"What is TIM-3 and why is it important in cancer immunotherapy?\",\"answer\":\"TIM-3 is an immune checkpoint receptor expressed across multiple immune cell types.
