26814963 Schizophrenia risk from complex variation of complement component 4
26800705 C4A and C4B gene copy numbers are stronger risk factors for juvenile-onset than for adult-onset systemic lupus erythematosus
26678451 Data indicate Ig-like transcript 4 (ILT4) as a cellular receptor for complement split products (CSPs) complement component 4d (C4d).
26517116 The interaction between C4BP and Leptospira interrogans LcpA, LigA and LigB is sensitive to ionic strength and inhibited by heparin.
26305533 Carrying no copies of C4B significantly increases the risk of cCSC, whereas carrying three C4B copies is protective.
26151608 Isolated C4d deposition and isolated interstitial inflammation appear to be benign lesions, but C4d deposition in association with interstitial inflammation in the biopsy is strongly associated with the development of chronic graft dysfunction.
26071493 Suggest a prominent prognostic value of C4d staining as a rejection marker in ABO compatible kidney transplantation.
26031580 C4d-negative acute antibody-mediated graft rejection resembles C4d-positive aAMR in terms of clinical and pathological features. C4d positivity has no influence on short-term outcome.
25894167 Late antibody/C4d-mediated rejection can emerge soon after the modification of immunosuppressive drug dosages and may be responsible for graft dysfunction or loss.
25799154 Elevated levels of the complement activation product C4d in bronchial fluids is associated with lung cancer.
