Plasma Adenosine Deaminase (ADA)-1 and -2 Demonstrate Robust Ontogeny Across the First Four Months of Human Life

open access: yesFrontiers in Immunology, 2021
BackgroundHuman adenosine deaminases (ADAs) modulate the immune response: ADA1 via metabolizing adenosine, a purine metabolite that inhibits pro-inflammatory and Th1 cytokine production, and the multi-functional ADA2, by enhancing T-cell proliferation ...

Treatment of Severe Refractory Hematuria due to Radiation-Induced Hemorrhagic Cystitis with Dexamethasone

open access: yesCase Reports in Medicine, 2017
Treatment of pelvic neoplasms with radiotherapy may develop sequelae, especially RHC. An 85-year-old male patient was admitted to a hospital emergency with gross hematuria leading to urinary retention and was diagnosed with RHC.

Homeostasis as the Mechanism of Evolution. [PDF]

open access: yes, 2015
Homeostasis is conventionally thought of merely as a synchronic (same time) servo-mechanism that maintains the status quo for organismal physiology. However, when seen from the perspective of developmental physiology, homeostasis is a robust, dynamic ...

Ontogeny of the ostracod Conchoprimitia osekensis (Pribyl, 1979) from the Darriwilian of the Prague Basin (Czech Republic) [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
The ontogeny of the species Conchoprimitia osekensis (Pribyl, 1979) from the Šárka Formation (lower and middle Darriwilian) is evaluated. Eight ontogenetic stages (A-8 to A-1) and one adult specimen are described and illustrated. This study displays that

Advances in proteomics: characterization of the innate immune system after birth and during inflammation

open access: yesFrontiers in Immunology, 2023
Proteomics is the characterization of the protein composition, the proteome, of a biological sample. It involves the large-scale identification and quantification of proteins, peptides, and post-translational modifications.

Ontogeny of Tumor-Associated Macrophages

open access: yesFrontiers in Immunology, 2019
Tumor-associated macrophages (TAM) represent the main immune cell population of the tumor microenvironment in most cancer. For decades, TAM have been the focus of intense investigation to understand how they modulate the tumor microenvironment and their ...

Origin and ontogeny of lung macrophages: from mice to humans

open access: yesImmunology, 2019
Macrophages are tissue‐resident myeloid cells with essential roles in host defense, tissue repair, and organ homeostasis. The lung harbors a large number of macrophages that reside in alveoli. As a result of their strategic location, alveolar macrophages
