Emerging role of C5aR2: novel insights into the regulation of uterine immune cells during pregnancy

Frontiers in Immunology
Pregnancy is a fascinating immunological phenomenon because it allows allogeneic fetal and placental tissues to survive inside the mother. As a component of innate immunity with high inflammatory potential, the complement system must be tightly regulated

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 C5a Receptor 1 Exacerbates the Pathophysiology of N. meningitidis Sepsis and Is a Potential Target for Disease Treatment

mBio, 2018
Sepsis caused by Neisseria meningitidis (meningococcus) is a rapidly progressing, life-threatening disease. Because its initial symptoms are rather unspecific, medical attention is often sought too late, i.e., when the systemic inflammatory response is ...

Ischemia–Reperfusion Injury: Molecular Mechanisms and Therapeutic Interventions

MedComm, Volume 7, Issue 7, July 2026.
Multiorgan ischemia–reperfusion injury begins with ischemia‐induced ATP depletion and ionic imbalance, followed by reperfusion‐triggered mitochondrial ROS/RNS bursts, regulated cell death, and DAMP release. Sterile inflammation converges on endothelial–immune–coagulation crosstalk, where NETs drive immunothrombosis, no‐reflow, and remote organ injury ...

Decoding Undesirable Inflammatory Responses of Nucleic Acid‐Delivering Lipid Nanoparticles

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Lipid nanoparticles (LNPs) enable efficient nucleic acid delivery, but their immunogenicity is a double‐edged sword. This review explores LNP‐driven innate and adaptive immunity, covering lipid components, endosomal escape, and nucleic acid sensing.

Extracellular Vesicles as Drivers of Lung Endothelial Dysfunction in ARDS: Mechanisms and Therapeutic Opportunities

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how extracellular vesicles from diverse pulmonary and extrapulmonary sources contribute to endothelial dysfunction in ARDS and evaluates emerging endothelial‐targeted therapies for their potential to mitigate EV‐mediated pathogenic mechanisms.

Anaphylatoxin C5a Regulates 6-Sulfo-LacNAc Dendritic Cell Function in Human through Crosstalk with Toll-Like Receptor-Induced CREB Signaling

Frontiers in Immunology, 2017
Activation of antigen-presenting dendritic cells (DCs) and the complement system are essential early events in the immune defense against invading pathogens.

Decoding the Factor H‐Related Proteins: Gatekeepers of Complement Dysregulation in AMD

European Journal of Immunology, Volume 56, Issue 6, June 2026.
This review will explore the role of the factor H‐related (FHR) proteins in age‐related macular degeneration (AMD), their accumulation in the outer blood/retinal barrier, and how they may contribute to barrier dysfunction and inflammation. ABSTRACT Age‐related macular degeneration (AMD) is the third most common form of blindness in the Western world ...

Site‐specific mutagenesis of residues in the human C5a anaphylatoxin which are involved in possible interaction with the C5a receptor [PDF]

European Journal of Biochemistry, 1994
To check and clarify existing data on receptor‐interacting residues in the human C5a anaphylatoxin, we tested mutant C5a proteins obtained by site‐directed mutagenesis of a recombinant human C5a (rhC5a) cDNA clone for structural and functional integrity.

Shifting From Systemic to Precision‐Targeted Complement Therapies: Opportunities and Hurdles

European Journal of Immunology, Volume 56, Issue 6, June 2026.
Complement therapeutics have expanded considerably, but systemic inhibitors remain limited by infection risks, breakthrough events, and loss of physiological functions. Emerging targeted approaches aim for organ‐, tissue‐, or cell‐specific modulation of complement activity, potentially offering greater precision while reducing treatment burden and ...
