Table 1. T2R-associated disorders and diseases.

T2R type Affected system Effects Reference
T2R38 Human upper respiratory system T2R38 genotype is correlated with susceptibility, severity, and prognosis of chronic rhinosinusitis, as well as biofilm formation in chronic rhinosinusitis patients Lee et al., 2012; Lee and Cohen, 2013; Adappa et al., 2014, 2016a,b,c
Human colorectal cancer T2R38 nonfunctional group has an increased risk of colorectal cancer in a population of Caucasian origin Carrai et al., 2011
Human gingiva T2R38 genotype is associated with gingival innate immunity and the risk of dental caries Wendell et al., 2010; Gil et al., 2015
Human colonic mucosa Increased number of T2R38 immunoreactive cells in overweight and obese subjects Latorre et al., 2016
T2R19 Blood glucose T2R19 haplotype is associated with altered glucose and insulin homeostasis Dotson et al., 2008
T2R50 Human heart T2R50 SNPs (ID rs1376251) have a strong association with cardiovascular disease Shiffman et al., 2008
T2R42 Thyroid Thyroid-expressed T2R42 SNP (SNP type L196F) is associated with differences in circulating levels of thyroid hormones Clark et al., 2015
T2R16 Longevity An upstream position polymorphism of T2R16 is significantly associated with longevity Campa et al., 2012
T2Rs Human leukocytes 10 T2Rs are up-regulated in leukocytes in severe asthma patients Orsmark-Pietras et al., 2013
T2Rs Human Parkinson’s disease patients’ brains T2R5 and T2R50 are decreased, whereas T2R10 and T2R13 are augmented at both premotor and parkinsonian stages in the frontal cortex area Garcia-Esparcia et al., 2013
Human schizophrenia patients’ brains T2R4, T2R5, T2R14, and T2R50 are down-regulated in the dorsolateral prefrontal cortex Ansoleaga et al., 2015
T2R4 Human breast cancer T2R4 is down-regulated in breast cancer cells Singh et al., 2014
T2R105 Mouse testes Depletion of T2R105 results in smaller testes and leads to male infertility Li and Zhou, 2012
Mouse glomerulus and renal tubule Ablation of T2R105-positive cells causes an increase in the size of the glomerulus and renal tubule and a lower cell density in the glomerulus Liu et al., 2015
T2R126, T2R135, and T2R143 Mouse heart Starvation increases the expression of these T2Rs by two- to threefold Foster et al., 2013
