Article Abstract
The complement system is part of the innate immunity. It is a multifunctional system including more than 30 plasma and membrane proteins. These are activated by an enzymatic cascade and proteolytic reactions producing activating fragments. Complement is : 1) among the first line of defense towards a pathogen, 2) increasing efficacy of the acquired immunity, 3) responsible for the elimination of immune complexes apoptotic and or necrotic cells (waste removal function) and many other cellular and tissue functions. The aim of this article is to analyze the consequences of complement dysregulation in the development of various diseases.
Background: The World Health Organization (WHO) recommends HIV self-testing (HIVST) to complement the existing HIV testing services. Pursuant to this, Rwanda approved the over-the-counter sale of Oral Quick HIV self-tests in community pharmacies, facilitating home testing and addressing accessibility issues. However, the availability and affordability of HIVSTs in these settings remains unexplored.

Streptococcus oralis is a commensal oral bacterium that acts as an opportunistic pathogen, causing systemic diseases, such as infective endocarditis and aspiration pneumonia. However, the specific molecular mechanisms underlying its transition from commensal to pathogenic state remain unclear. In this study, to further elucidate the mechanisms underlying virulence expression, we identified and characterized the cell surface-associated ecto-5'-nucleotidase (Nt5e) in S.
To analyze the clinical characteristics of cardiovascular disease in systemic lupus erythematosus (SLE) patients and identify risk factors for predicting the occurrence of cardiovascular disease in SLE patients. Clinical data of 110 SLE patients were randomly selected from the Tongde Hospital of Zhejiang Province clinical medical record database, including 50 patients with cardiovascular disease and 60 patients without. Clinical data, blood biochemistry indicators, antibody detection results, and complement levels were collected.
Objective: To explore the relationship between leukocyte count and renal function in patients with lupus nephritis (LN).
Methods: We performed a retrospective cross-sectional study of 100 patients with LN admitted to the Department of Nephrology between 1 January 2015 and 30 December 2023. Based on tertile of leukocyte count, they were allocated to Low, Medium, or High groups.
The interception of blood-borne bacteria in the liver defines the outcomes of invasive bacterial infections, but the mechanisms of this antibacterial immunity are not fully understood. This study shows that natural antibodies (nAbs) to capsules enable liver macrophage Kupffer cells (KCs) to rapidly capture and kill blood-borne encapsulated bacteria in mice. Affinity pulldown with serotype-10A capsular polysaccharides (CPS10A) of Streptococcus pneumoniae (Spn10A) led to the identification of CPS10A-binding nAbs in serum.
