The relationship of salivary molecule concentration to blood (or saliva/plasma ratio; S/P) is influenced by serum/saliva pH, molecular pKa, molecular weight, lipophilicity, and protein binding.

In the past, the characterization of even a single human gene was a painstaking process, requiring years of effort. Recent developments in the areas of cloning vectors, DNA sequencing, and computer technology have merged to greatly accelerate the rate at which human genes can be isolated, sequenced, mapped, and characterized.

Polyphenols (tannins) in the diet not only precipitate oral proteins, producing an astringent sensation, but also interact with dietary proteins and digestive enzymes in the gut, resulting in a variety of antinutritive and toxic effects.
Salivary proline-rich proteins (PRPs), which are secreted into the oral cavity, form complexes with and precipitate dietary polyphenols, and thus, they. From the sequences obtained, it is likely that these peptides are derived from proteolysis of the hydroxyapatite-interactive human salivary proteins, histatins, proline-rich proteins, and statherins.
Tannins are well-known food polyphenols that interact with proteins, namely, salivary proteins. This interaction is an important factor in relation to their bioavailability and is considered the basis of several important properties of tannins, namely, the development of astringency.
It has been generally accepted that astringency is due to the tannin-induced complexation and/or precipitation Cited by: Human salivary mucin MG1 selectively forms heterotypic complexes with amylase, proline-rich proteins, statherin, and histatins.

For almost all proteins, there is substantial reactivity towards polyphenol sources, denoted by the reduction in band density. This is more marked for seed tannins which are more reactive toward salivary by: This confirmed the interaction between EGCG and human salivary α-amylase.
The assay was confirmed by using porcine α-amylase as a standard (unpublished). Rotor Cited by: 2. Other main limitations of salivary diagnostics are the contamination and variable nature of saliva. 17 The complexity of biological and physiological processes creates new challenges on data processing and analysis, ability to quantify proteins and to analyze protein complexes, etc.
18 Therefore, it is recommended to focus more on salivary. Human saliva is an ideal body fluid for developing non-invasive diagnostics. Saliva contains naturally-occurring nanoparticles with unique structural and biochemical characteristics. The salivary exosome, a nanoscale extracellular vesicle, has been identified as a highly informative nanovesicle with clinically-relevant information.
Salivary exosomes have brought forth a pathway and mechanism Cited by: 5. The dietary consumption of grape and its products is associated with a lower incidence of degenerative diseases such as cardiovascular disease and certain types of cancers.
Most recent Characterization of the molecular nature of the interaction of human salivary histatins book has focused on the bioactive phenolic compounds in grape. Anthocyanins, flavanols, flavonols and resveratrol are the most important grape polyphenols because they possess many biological activities Cited by: Oviduct-specific glycoprotein also known as oviductal glycoprotein (OGP) or estrogen-dependent oviduct protein (EGP) or mucin-9 (MUC9) is a protein that in humans is encoded by the OVGP1 gene.
Function. Oviduct-specific glycoprotein is a large, carbohydrate-rich, epithelial glycoprotein with numerous O-glycosylation sites located within threonine, serine, and proline-rich tandem s: OVGP1, CHIT5, EGP, MUC9, OGP.

With the common name “dental plaque,” oral microbial communities are some of the most complex microbial floras in the human body, consisting of more than different bacterial species (1,).Extensive clinical studies have indicated that the oral microbial flora is responsible for two major human diseases: dental caries (tooth decay) and periodontitis (gum disease) (28,Cited by: Aim: The aim of the present review article is to establish a systematic review to describe the role of various salivary components such as pH, buffering capacity, proteins, electrolyte, antioxidant, enzymes, and minerals in occurrence and initiation of dental caries in participants with and without dental caries.
Results: A total of articles were retrieved through electronic by: 1. Mucins in human saliva are currently classed into two main categories, the high molecular weight MUC5B mucins and the low molecular weight MUC7 mucins.
In our study, a sedimentation coefficient for mucin of ~4S was compared against a standard, Sigma bovine submaxilllary mucin (4S), which had a molecular weight of ~ kDa (unpublished reports). AbstractHistatins are histidine-rich peptides present in the saliva of humans and higher primates and have been implicated in the protection of the oral cavity.
Histatin 1 is one of the most abundant histatins and recent reports show that it has a stimulating effect on cellular adherence, thereby suggesting a role in maintaining the quality of the epithelial barrier and stimulating mesenchymal Author: Irene A. van Dijk, Enno C.I.

AbstractThis work describes the current state of research on the potential relationship between protein content in human saliva and dental caries, which remains among the most common oral diseases and causes irreversible damage in the oral cavity.
An understanding the whole saliva proteome in the oral cavity could serve as a prerequisite to obtaining insight into the etiology of tooth decay at Author: Galina Laputková, Vladimíra Schwartzová, Juraj Bánovčin, Michal Alexovič, Ján Sabo.
This chapter provides an in-depth account of defensins, and ties together the roles of other antimicrobial peptides and proteins that together contribute to mucosal innate host defense.
While the focus is on defensins and antimicrobial peptides from humans, peptides from other species are also included where appropriate. The structural and functional relationships between these three classes Cited by: Salivary secretion is under autonomic nervous control and thus regulated by the parasympathetic and sympathetic nervous system.
Impulses that arise from activation of chemoreceptors in the taste buds are carried to the salivatory nuclei in the medulla oblongata through the trigeminal (V), facial (VII), glossopharyngeal (IX) and vagal (X) nerves (NN.), whereas impulses from activation of Cited by: Human salivary IgA inhibits the adherence of oral streptococci and Candida albicans to buccal epithelial cells (, ).

Here, we have analyzed gingival crevicular fluid, an oral fluid comprising a serum transudate and tissue exudates, by LC−MS/MS using Fourier transform ion Cited by: The nature of the interaction between these salivary proteins and polyphenols depends on several factors, among which protein characteristics and the type of polyphenol.
Salivary proteins such as acidic PRPs and statherins present lower selectivity towards polyphenol structures, comparatively to histatins and cystatins [ 46 ].Author: Elsa Lamy, Martine Morzel, Lénia Rodrigues, Cristina Pinheiro, Ana Rodrigues Costa, Célia Miguel Ant. At the molecular level, the binding and precipitation of salivary proteins with astringent compounds is thought to form the basis for astringency, although the exact molecular mechanism and how it relates to the sensory perception is still unclear and is thought to vary with the nature of the astringent (Gibbins & Carpenter, ; Lee, Ismail Cited by: 2.

Mucosal surfaces account for the vast majority of HIV transmission. In adults, HIV transmission occurs mainly by vaginal and rectal routes but rarely via oral route. By contrast, pediatric HIV infections could be as the result of oral route by breastfeeding. As such mucosal surfaces play a crucial role in HIV acquisition, and spread of the virus depends on its ability to cross a mucosal by: 75 a high local but low systemic concentration Further research may lead to a better understanding both its toxicity to humans and interaction with microbial targets, which could lead to more pharmaceutical and commercial interests.
Histatin-5 Histatins (Hs) are found in the saliva of higher primates and named due to their histidine rich.
