In the present chapter, we review the literature supporting a role for chemokines in angiogenesis and lymphangiogenesis. We highlight that chemokines exert both pro- and antiangiogenic roles either by acting directly on endothelial cells or by recruiting leukocytes that, in turn, secrete angiogenic mediators.

Excess body weight and obesity are typified by 'low-degree' chronic inflammation and are associated with an increased risk of atherosclerosis, diabetes, fatty liver disease, autoimmune diseases and cancer. All these pathological conditions are characterized by chronic inflammation, abnormal cytokine production, elevated acute-phase reactants, and the activation of several inflammatory signaling pathways. In this context, the discovery of the adipose tissue-derived hormone leptin has shed fundamental insights on how these processes might occur. Leptin represents a link among metabolic disorders and immune tolerance; indeed, leptin can negatively affect the generation and proliferation of Treg cells, key players in this context. Treg cells play also a central role in tumor progression; different reports have proposed that tumor microenvironment can induce the recruitment of Treg cells which can promote tumor tolerance and angiogenesis through expression of suppressive molecules, cytokines and angiogenic factors (i.e. vascular endothelial growth factor, leptin). This work aims to discuss some of the most recent advances on the relationship between angiogenesis, leptin and immune tolerance, focusing on the role of Treg cell function in this context.</p>","PeriodicalId":86023,"journal":{"name":"Chemical immunology and allergy","volume":"99 ","pages":"155-69"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000353557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"31853970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prekallikrein and HK circulate as a bimolecular complex. Initiation of the cascade upon binding to negatively charged surfaces (or macromolecules) is dependent on factor XII autoactivation, conversion of prekallikrein to kallikrein, and a feedback activation of factor XII by kallikrein. The latter reaction is extremely rapid relative to factor XII autoactivation. The kallikrein then digests HK to liberate bradykinin. The natural surface appears to be vascular endothelial cells which express binding proteins for factor XII and HK, and activation can proceed along the cell surface. Recent findings demonstrate that prekallikrein has enzymatic activity separate from that of kallikrein such that it can stoichiometrically bind and cleave HK to liberate bradykinin. It is normally prevented from doing so by the plasma C1 inhibitor. Release of heat shock protein 90 (HSP-90) from endothelial cells can convert prekallikrein to kallikrein (stoichiometrically) within the prekallikrein-HK complex, even in the absence of factor XII, and the prekallikrein-HK complex can autoactivate to generate kallikrein if phosphate is the buffering ion. The effects of phosphate ion and HSP-90 are additive. Thus, an active site appears to be induced in prekallikrein by binding to HK and any of the aforementioned reactions can generate kallikrein prior to factor XII activation by autoactivation of the HK-PK complex. This brief review highlights the major discoveries made over the past 50 years which have led to our current concepts regarding the constituents and mechanisms of activation of the plasma bradykinin-forming cascade.</p>","PeriodicalId":86023,"journal":{"name":"Chemical immunology and allergy","volume":"100 ","pages":"205-13"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000358739","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32422141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cortisone and ACTH were found to be very beneficial in the treatment of rheumatoid arthritis and Kendall, Reichstein and Hench received the Nobel Prize in Physiology and Medicine for this work in 1950. Bordley and colleagues first showed that ACTH was very beneficial in the treatment of allergic diseases in 1949, but the use of systemic glucocorticoids was limited by side effects. Inhaled glucocorticoids were discovered from topical steroids developed for skin inflammation and beclomethasone dipropionate was introduced in 1972, initially in low doses but later in higher doses, and became the standard treatment for persistent asthma. Subsequently, inhaled glucocorticoids were combined with long-acting β2-agonists in combination inhalers for even greater therapeutic benefit.

By the beginning of the 20th century, asthma was seen to be a unique illness characterized by 'spasmodic afflictions of the bronchial tubes'. Consistent with the nature of asthma as a complex disease, the models for asthma pathogenesis have become increasingly complex. Research has moved from antiquated ideas to a descriptive functional approach to one that relies on pathophysiology in cellular and molecular biology, immunology, microbiology and genetics/genomics. As more advanced technologies for measuring lung function were developed, the features of asthma were steadily unraveled and its pathophysiology clarified. Asthma was shown to be associated with transient increases in airway resistance, reductions in forced expiratory volumes and flows, hyperinflation of the lungs and increased work of breathing, as well as abnormalities in the distribution of ventilation, perfusion and arterial blood gases.
