Background: Saliva being an important biological fluid of our body contains both specific and nonspecific protective factors which form an integral part of our immune system. Salivary proteins play a substantial role in protecting humans against infection. Their level in oral cavity is subject to constant variations which is dependent on various factors.
Purpose: The purpose of the study was to compare the levels of salivary proline-rich proteins (PRPs), glycoproteins, amylase bands, and salivary pH in children with early childhood caries before and after treatment using gel electrophoresis.
Materials And Methods: The whole salivary pH, mean protein concentrations, and electrophoretic profiles of the salivary proteins were measured using sodium dodecylsulfate-polyacrylamide gel electrophoresis in both pre- and posttreatment groups. Statistical analysis was done using Statistical Package for Social Sciences (SPSS) version 15.0 software. Chi-square test and independent t-test were used to further compare the results.
Results: The results were statistically significant in all the groups. There was variation in pre- and posttreatment values seen.
Conclusion: Salivary proteins (glycoproteins, PRPs, and amylase) establish an imperative defense mechanism as antimicrobial agents.

Tick salivary proteins are crucial for efficient and successful tick feeding. Most of them are still uncharacterized, especially those involved in the formation of tick cement. Tick salivary protein PA107 is a putative cement protein, which is transcribed in salivary glands during the initial phase of tick feeding.

Salivary gland diseases encompass a broad range of conditions, including autoimmune, inflammatory, obstructive, and neoplastic disorders, significantly impacting oral health and overall well-being. Recent research has highlighted the crucial role of exosomes, small extracellular vesicles, in these diseases. Exosomes mediate intercellular communication by transferring bioactive molecules such as proteins, microRNAs, and lipids, positioning them as potential diagnostic biomarkers and therapeutic agents.

Kounis syndrome also known as allergic myocardial infarction, represents the simultaneous occurrence of acute coronary syndromes with allergic or hypersensitivity reactions. We present a case of a 58-years-old male who developed anaphylaxis following a leech bite, leading to myocardial infarction despite the absence of prior allergic history. He was entubated and cardiopulmonary resusciation had been performed for 10 minutes.

SARS-CoV-2-related proteins, ACE2 and TMPRSS2, are determinants of SARS-CoV-2 infection. Although these proteins are expressed in oral-related tissues, their expression patterns and modulatory mechanisms in the salivary glands remain unknown. We herein showed that full-length ACE2, which has both a fully functional enzyme catalytic site and high-affinity SARS-CoV-2 spike S1-binding sites, was more highly expressed in salivary glands than in oral mucosal epithelial cells and the lungs.
