Special Issue Information
Dear Colleagues,
Kinins are short-lived peptides that cause pain, arteriolar dilation, increased vascular permeability and contractions in smooth muscle. They are generated from kininogens through proteolysis by kallikreins. Together, these proteins and peptides, as well as their regulators, constitute the components of the kallikrein–kinin system (KKS).
Kinin production is dependent upon serine proteases, namely, plasma and tissue kallikreins. A prekallikrein is the precursor of plasma kallikrein that liberates bradykinin after it is activated by factor XIIa or enzymes. The activation and activity of both plasma kallikrein and factor XIIa are under the control of inhibitor C1, a serine protease inhibitor (serpin) protein. A deficiency of inhibitor C1 presents as a disorder of hereditary angioedema, a condition where there is less regulation of the production of vasoactive peptide bradykinin.
Kinins are inactivated by metallo-peptidases, such as: (i) carboxypeptidases, alias kininase I, that are present in two forms, circulating carboxypeptidase N and membrane-bound carboxypeptidase M, which remove C-terminal arginine residues of kinins; (ii) angiotensin-I-converting enzyme, alias kininase II, inactivating a number of peptide mediators, including bradykinin; (iii) aminopeptidase P that inactivates desArg9-kinins; (iv) neutral endopeptidase, which also deactivates kinins.
Kinin receptors B2 (constitutive) and B1 (inducible) are G-protein-coupled receptors that mediate activation signals through multiple tissues, including endothelial cells.
Kinins are directly, or indirectly, involved in many inflammatory diseases. If defects of the KKS in diseases are not generally recognized, the gain-of-function of one of the KKS component has been recognized to participate in hereditary angioedema. The KKS has been the subject of much research due to its relationship to inflammation and blood pressure systems. Kinins are generally considered to be inflammatory mediators, the accumulation of which causes the dilation of blood vessels, increased vascular permeability and pain, due to acting on phospholipase, with a subsequent release of arachidonic acid and prostaglandin production.
Similar to the KININ2022 conference, this research topic aims to expand on current knowledge data, recent progress and future plans in the field of kinins and the KKS, along with their relationships to diseases.
Within this Special Issue, we hope to publish original research articles, reviews, systematic reviews, mini reviews, methods, policy and practice reviews, hypotheses and theories, perspectives, clinical trials, case reports and community case studies, classifications, data reports, policy briefs, brief research reports, study protocols and Opinion articles, all of which would cover:
- Kallikrein–kinin system in biology;
- Kinin receptors: pharmacology, signalling and regulation;
- Animal models;
- Kallikrein–kinin system in diseases;
- Kallikrein–kinin system: drugs, inhibitors and antagonists.
We look forward to your participation. Thank you for your consideration.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
