![]() ![]() ![]() NSG mice transplanted with these BCP-ALL cells were monitored for survival. We analyzed the consequences of increasing ST6Gal1 expression in a diagnosis sample using lentiviral transduction. B-cell precursor acute lymphoblastic leukemias (BCP-ALLs) with differentiation arrest at various stages of early B-cell development have widely different expression levels of ST6GAL1 at diagnosis, with high ST6Gal1 in some but not in other relapses. Expression of ST6Gal1 increases as B cells undergo normal B-lineage differentiation. The sialyltransferase ST6Gal1, with high expression in specific hematopoietic cell types, is the only enzyme thought to catalyze the terminal addition of sialic acids in an α2-6-linkage to galactose on N-glycans in such cells. Glycosylation is thought to play a key role in such interactions. Normal early human B-cell development from lymphoid progenitors in the bone marrow depends on instructions from elements in that microenvironment that include stromal cells and factors secreted by these cells including the extracellular matrix. This mechanism of action gives rationale to support the significant amelioration of disease and good safety profile in clinical trials, as by enabling the "self" recognition mechanism of CD22 via trans binding to α2,6 sialic acid ligands on autologous cells, SM03 specifically restores immune tolerance of B cells to host tissues without affecting the normal B cell immune response to pathogens. This in turn increased the activity of the downstream immunomodulatory molecule Src homology region 2 domain-containing phosphatase 1 (SHP-1) and decreased BCR-induced NF-κB activation in human B cells and B cell proliferation. SM03 could disturb the CD22 homomultimeric configuration through disrupting cis binding to α2,6-linked sialic acids, induce rapid internalization of CD22 from the cell surface of human B cells, and facilitate trans binding between CD22 to human autologous cells. ![]() CD22, an inhibitory coreceptor of the BCR, is a potential immunotherapeutic target against autoimmune diseases. We propose the success of SM03 as a therapeutic to systemic autoimmune diseases is through the utilization of a novel mechanism of action unique to SM03. SM03 showed good safety and efficacy in phase I systemic lupus erythematosus and phase II moderate to severe rheumatoid arthritis clinical trials. She also participated in the RB Battles Season 2 event, but lost to Hyper in the first round.SM03, an anti-CD22 recombinant IgG1 mAb, is currently in a phase III clinical trial for the treatment of rheumatoid arthritis (NCT04312815). She uploads content centered around Adopt Me and Welcome to Bloxburg.

You can still play the Bloxburg game mode by heading to Coeptus’ (the developer) profile and clicking creations. ![]() You don’t need to worry though, as it appears to simply be a visual glitch. The popular game hasn’t been deleted, but for some reason the game is appearing as for many players.
