CD6 immunotherapy to treat psoriasis and rheumatoid arthritis has reached the clinical trial stage with apparent success, and targeting CD6 with mAbs is being used in several animal models of autoimmunity and neuroinflammation with promising indications. However, the mode of action of the therapeutic CD6 mAbs is far from being understood, reflecting the(More)
We propose a modification of an algorithm introduced by Martínez (1987) for solving nonlinear least-squares problems. Like in the previous algorithm, after the calculation of an approximated Gauss-Newton directiond, we obtain the next iterate on a two-dimensional subspace which includesd. However, we simplify the process of searching the new point, and we(More)
The scavenger receptor cysteine-rich (SRCR) family comprises a group of membrane-attached or secreted proteins that contain one or more modules/domains structurally similar to the membrane distal domain of type I macrophage scavenger receptor. Although no all-inclusive biological function has been ascribed to the SRCR family, some of these receptors have(More)
OBJECTIVES To evaluate the role of S100A4, a calcium-binding regulator of nonmuscle myosin assembly, for T-cell responses in rheumatoid arthritis. METHODS Arthritis was induced in the methylated bovine serum albumin (mBSA)-immunized mice lacking the entire S100A4 protein (S100A4KO) and in wild-type counterparts treated with short hairpin ribonucleic acid(More)
