The impact of the complement receptors C3aR1 and C5aR1 on the progression of melanoma

The Journal of Immunology, 2023
Abstract Melanoma is an aggressive skin cancer that develops from the malignant transformation of pigment-producing skin cells, melanocytes. The incidence of cutaneous melanoma is remarkably high, with an estimated number of new cases in the United States in 2022 close to 100,000 patients.

Double Deletion of C5aR1 and C5aR2 during Streptococcal Pneumonia

The Journal of Immunology, 2020
Abstract The complement system is essential for the clearance of encapsulated bacteria such as Streptococcus pneumoniae (Spn), recognized as a major pathogen of pneumonia. Yet, it is not entirely clear whether C5 and its activation product C5a have beneficial or detrimental effects on the outcome of Spn infection.

PTX3 Deficiency Aggravates Periodontitis by the Complement C5a-C5aR1 Axis

Journal of Dental Research
Dysregulation of the complement system plays a critical role in periodontitis progression. In addition to the harmful effects of biofilm, aberrant expression of complement regulatory proteins is also a potential cause of periodontitis. Pentraxin 3 (PTX3) is involved in complement activation and regulation, seeking a balance between amplifying ...

Elucidating the role of neuronal C5aR1

The complement system, traditionally considered a peripheral component of the body's innate immune response, comprises approximately 50 membrane-bound and soluble proteins that form a rapid and potent enzymatic cascade. This cascade facilitates the opsonisation, phagocytosis, and osmotic lysis of invading pathogens and detrimental host tissue.
