Decoding Undesirable Inflammatory Responses of Nucleic Acid‐Delivering Lipid Nanoparticles

Advanced Science, EarlyView.
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.

The “C3aR Antagonist” SB290157 is a Partial C5aR2 Agonist

Frontiers in Pharmacology, 2021
Innate immune complement activation generates the C3 and C5 protein cleavage products C3a and C5a, defined classically as anaphylatoxins. C3a activates C3aR, while C5a activates two receptors (C5aR1 and C5aR2) to exert their immunomodulatory activities ...

Therapeutic approaches with intravitreal injections in geographic atrophy secondary to age-related macular degeneration: current drugs and potential molecules [PDF]

, 2019
The present review focuses on recent clinical trials that analyze the efficacy of intravitreal therapeutic agents for the treatment of dry age-related macular degeneration (AMD), such as neuroprotective drugs, and complement inhibitors, also called ...

Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

A computational model for the evaluation of complement system regulation under homeostasis, disease, and drug intervention. [PDF]

PLoS ONE, 2018
The complement system is an intricate defense network that rapidly removes invading pathogens. Although many complement regulators are present to protect host cells under homeostasis, the impairment of Factor H (FH) regulatory mechanism has been ...

Induction of Complement C3a Receptor Responses by Kallikrein-Related Peptidase 14 [PDF]

The Journal of Immunology, 2013
Abstract Activation of the complement system is primarily initiated by pathogen- and damage-associated molecular patterns on cellular surfaces. However, there is increasing evidence for direct activation of individual complement components by extrinsic proteinases as part of an intricate crosstalk between physiological effector systems ...

Targeting C3a and C5a Signaling—A Game Changer for Cancer Therapy?

Biology
Emerging evidence reveals a significant shift in understanding the complement system’s role in cancer, where activation of a complement within the tumor microenvironment (TME) fuels tumor growth and metastasis instead of suppressing it.

Complement Activation and Organ Damage After Trauma—Differential Immune Response Based on Surgical Treatment Strategy

Frontiers in Immunology, 2020
Background: The complement system is part of the innate immunity, is activated immediately after trauma and is associated with adult respiratory distress syndrome, acute lung injury, multiple organ failure, and with death of multiply injured patients ...

Paths reunited: initiation of the classical and lectin pathways of complement activation [PDF]

, 2010
Understanding the structural organisation and mode of action of the initiating complex of the classical pathway of complement activation (C1) has been a central goal in complement biology since its isolation almost 50 years ago.

Navigating adverse immunostimulation: A practical guide for clinical researchers

British Journal of Clinical Pharmacology, EarlyView.
Problem Setting As drug development moves towards more complex products, early clinical development programmes are increasingly hampered by unwanted and/or unexpected activation of the immune system (adverse immune stimulation, AIS). Solution At the Centre for Human Drug Research, we have introduced standardized procedures to make AIS manageable, while
