TIGIT
TIGIT is a transmembrane glycoprotein comprising one immunoglobulin variable (IgV) domain, a type I transmembrane domain, and a cytoplasmic tail with an immunoreceptor tyrosine-based inhibitory motif (ITIM) and immunoglobulin tyrosine tail (ITT)-like motif.

Thymoquinone in Cancers Therapy
To date, natural products are widely used as pharmaceutical agents for many human diseases and cancers. One of the most popular natural products that have been studied for anticancer properties is thymoquinone (TQ). As a bioactive compound of Nigella sativa, TQ has shown anticancer activities through the inhibition of cell proliferation, migration, and invasion. The anticancer efficacy of TQ is being investigated in several human cancers such as pancreatic cancer, breast cancer, colon cancer, hepatic cancer, cervical cancer, and leukemia.

Thymoquinone and Cancer
Thymoquinone (TQ) is a bioactive molecule with anticancer as well as anti-inflammatory activities via the downregulation of several chemokines and cytokines. Administering it as a nanoformulation increases its therapeutic value.

Thymoquinone
Thymoquinone (TQ), the chief active constituent of Nigella sativa (NS), shows very valuable biomedical properties such as antioxidant, antimicrobial, anticancer, anti-inflammatory, antihypertensive, hypoglycemic, antiparasitic and anti-asthmatic effects. Several studies have examined the pharmacological actions of TQ in the treatment of oral diseases but its potential role in periodontal therapy and regeneration is not yet fully defined.

Three-Dimensional Spheroids in Cancer Research
Three-dimensional (3D) cultures of cancer cells that better recapitulate in vivo cell environments emerged as scientifically accurate and low cost cancer models for preclinical screening and testing of new drug candidates before moving to expensive and time-consuming animal models.

Three-Dimensional Printing Technologies for Oral Films
The interest in buccal drug delivery is under consideration due to some distinct properties compared to the traditional pharmaceutical formulations for oral administration: significantly higher bioavailability, a faster absorption rate of the drug, and substantial compliance for special needs patients. Oral films are obtained through various technologies, from conventional tools to 3D and 4D printing approaches. Three-dimensional printing can solve the formulation problems of producing oral films (OFs).

Three-Dimensional In Vitro Cell Culture Models
Despite tremendous advancements in technologies and resources, drug discovery still remains a tedious and expensive process. Though most cells are cultured using 2D monolayer cultures, due to lack of specificity, biochemical incompatibility, and cell-to-cell/matrix communications, they often lag behind in the race of modern drug discovery. There exists compelling evidence that 3D cell culture models are quite promising and advantageous in mimicking in vivo conditions. It is anticipated that these 3D cell culture methods will bridge the translation of data from 2D cell culture to animal models. Although 3D technologies have been adopted widely these days, they still have certain challenges associated with them, such as the maintenance of a micro-tissue environment similar to in vivo models and a lack of reproducibility. However, newer 3D cell culture models are able to bypass these issues to a maximum extent.

Thiopurines’ Metabolites and Drug Toxicity
Thiopurines (comprising azathioprine (AZA), 6-mercaptopurine (6-MP), and 6-thioguanine) have been used for over 5 decades in the treatment of a myriad of disorders, including acute lymphoblastic leukemia (ALL), inflammatory bowel disease (IBD), auto-immune hepatitis (AIH), and also in the prophylaxis of rejection in organ transplant recipients. Many questions remain unanswered regarding therapeutic drug monitoring (TDM) utility with thiopurines. We performed a systematic review with inclusion of studies evaluating the relationship between thiopurines’ metabolites and drug toxicity. Meta-analysis of mean difference (MD), correlations and odds ratio (OR) was performed. We identified 21,240 records, 72 of which were eligible for meta-analysis. Levels of 6-thioguanine nucleotides (6-TGN) were higher in patients with leukopenia (MD 127.06 pmol/8 × 108 RBC) and gastrointestinal intolerance (MD 201.46 pmol/8 × 108 RBC), and lower in patients with hepatotoxicity (MD −40.6 pmol × 108 RBC). We established a significant correlation between 6-TGN and leukocytes (r = −0.21), neutrophils (r = −0.24) and alanine aminotransferase levels (r = −0.24). OR for leukopenia in patients with elevated 6-TGN was 4.63 (95%CI 2.24;9.57). An optimal cut-off of 135 pmol/8 × 108 RBC for leukopenia was calculated (sensitivity 75.4%; specificity 46.4%). 6-methylmercaptopurine ribonucleotides (6-MMPR) were significantly associated with hepatotoxicity (MD 3241.2 pmol/8 × 108 RBC; OR 4.28; 95%CI 3.20; 5.71). Levels of 6-MMPR measured in the first 8 weeks of treatment were associated with leukopenia. We conclude that TDM could be used to prevent thiopurines’ toxicity. As optimal metabolites level may vary according to indication, physicians may adapt posology to decrease toxicity without compromising efficacy.

Thiophene-Based Compounds
Thiophene derivatives provide useful intermediaries in various areas of science and industry, with a wide range of applications, and therapeutic properties. Thiophene derivatives attract both great academic interest, and interest from the agrochemical, pharmaceutical, and dye industries, as well. As to their biological and pharmacological applications, thiophene derivatives possess remarkable properties as antipsychotic, antianxiety, antifungal, antimicrobial, antioxidant, anticancer, and anti-inflammatory agents. The present work provides an update on the role of thiophene-based derivatives in inflammation processes.

Thiolated-Polymer-Based Nanoparticles
Thiomers (or thiolated polymers) have broken through as avant-garde approaches in anticancer therapy. Their distinguished reactivity and properties, closely linked to their final applications, justify the extensive research conducted on their preparation and use as smart drug-delivery systems (DDSs).
