Analysis of stimulated cells from the C1q-deficient patient on the presence of C1q, (A) Western blot analysis of cell lysates from stimulated PBMCs in reducing conditions, (B) non-reducing and non-denaturing conditions. (C) Western blot analysis of the supernatant of the PBMCs from the patient and the healthy donor (control) after 72 h of culturing in reducing conditions. (D) In non-reducing and non-denatured conditions, the cell lysates and supernatant were added in the same amount. (E) A schematic representation of intact C1q and low molecular weight (LMW)-C1q. In LMW-C1q, positive charges are introduced in the collagen-like tail due the amino acid exchange Gly-Arg at the N-terminal region [modified from Ref. (2)].
