Human Properdin Modulates Macrophage: Mycobacterium bovis BCG Interaction via Thrombospondin Repeats 4 and 5

Frontiers in Immunology, 2018
Mycobacterium tuberculosis can proficiently enter macrophages and diminish complement activation on its cell surface. Within macrophages, the mycobacterium can suppress macrophage apoptosis and survive within the intracellular environment. Previously, we

Complement alternative pathway activation in human nonalcoholic steatohepatitis. [PDF]

PLoS ONE, 2014
The innate immune system plays a major role in the pathogenesis of nonalcoholic steatohepatitis (NASH). Recently we reported complement activation in human NASH.

Complement Dysregulation in Obese Versus Nonobese Polycystic Ovary Syndrome Patients

Cells, 2023
Introduction: Upregulation of complement system factors are reported to be increased in polycystic ovary syndrome (PCOS) and may be due to obesity and insulin resistance rather than inherently due to PCOS.

Complement Inhibition in the Clinic: Are We Doing Enough to Protect Patients From Infection?

European Journal of Immunology, Volume 56, Issue 7, July 2026.
Excessive complement activation is implicated in a broad range of diseases. Therapeutic approaches targeting the complement cascade, from pathway‐selective inhibition to terminal blockade, can effectively control disease activity. However, increasing degrees of complement inhibition are associated with a heightened susceptibility to bacterial, viral ...

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

Interdisciplinary Medicine, Volume 4, Issue 4, July 2026.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Properdin Modulates Complement Component Production in Stressed Human Primary Retinal Pigment Epithelium Cells

Antioxidants, 2020
The retinal pigment epithelium (RPE) maintains visual function and preserves structural integrity of the retina. Chronic dysfunction of the RPE is associated with retinal degeneration, including age-related macular degeneration (AMD).

Exploring urine:serum fractional excretion ratios as potential biomarkers for lupus nephritis

Frontiers in Immunology, 2022
ObjectivesThe goal of this exploratory study is to determine if urine:serum fractional excretion ratios can outperform the corresponding urinary biomarker proteins in identifying active renal disease in systemic lupus erythematosus (SLE).MethodsThirty ...

Urine Proteomic Profiling at Admission Reveals Complement Biomarkers Linked to Alcohol‐Associated Liver Disease

Alcohol, Clinical and Experimental Research, Volume 50, Issue 6, June 2026.
Patients with alcohol‐associated hepatitis (AH) and alcohol‐cirrhosis (AC) show perturbations in complement. Complement activation pathways are perturbed in the urine of patients with AH and AC, and distinguish severe AH from AC. Complement perturbations can help physicians and researchers to understand the liver–kidney crosstalk in severe AH and AC ...

Protective role for properdin in progression of experimental murine atherosclerosis.

PLoS ONE, 2014
Genetic, dietary and immune factors contribute to the pathogenesis of atherosclerosis in humans and mice. Complement activation is an integral part of the innate immune defence but also shapes cellular responses and influences directly triglyceride ...
