Gene expression profiles of Siglec-14/THP-1 and Siglec-5/THP cell lines, with or without NTHi stimulation

Project description:Acquisition of a new strain of non-typeable Haemophilus influenzae (NTHi) is often associated with exacerbation of chronic obstructive pulmonary disease (COPD). We have previously reported that COPD patients who are homozygous null for SIGLEC14 gene is less susceptible to COPD exacerbation than those who have wild-type allele with functional SIGLEC14 gene. In order to gain insight into the mechanism behind the COPD exacerbation, and to find new clues that may lead to the discovery of objective biomarker of COPD exacerbation, Siglec-14/THP-1 and Siglec-5/THP-1 cell lines, which mimic monocytes from homozygous wild-type and homozygous SIGLEC14-null person, respectively, were incubated with or without NTHi, and their gene expression profiles were compared by using Affymetrix Human Genome U133 Plus 2.0 Array. Four samples (2 cell lines x 2 conditions) were analyzed. No replicates were made.

Proximity labeling and identification of the proteins that interact with Siglec-14 on THP-1 cells

Project description:Proteins that interact with Siglec-14 were identified by proximity labeling, followed by streptavidin affinity purification and proteomic analysis. MaxQuant software was used for the quantitative analysis of the proteins identified.

Proximity labeling of Siglec-1 counter-receptors on activated regulatory T cells using soluble Siglec-1-HRP multimers

Project description:Siglec-1 is a macrophage lectin-like receptor that mediates sialic acid-dependent cellular interactions. It was shown previously to promote inflammation in autoimmune disease through suppressing the expansion of regulatory T cells (Tregs). We have investigated the molecular basis for Siglec-1 binding to these cells using in vitro-induced Tregs. A proximity labelling and proteomics strategy were used to identify glycoproteins expressed by activated Tregs that may function as Siglec-1 counter-receptors.

Type-I interferon inducible genes 26 weeks after mCMV infection in Siglec-H wt and Siglec-H ko mice and their non infected controls

Project description:Type I interferons are critical anti-viral cytokines during virus infections and have also been implicated in the pathogenesis of systemic lupus erythematosus (SLE). The secretion of type I interferon of pDCs is modulated by Siglec-H, a DAP12 associated receptor on pDCs. We showed that Siglec-H deficient pDCs produce more of the type I interferon IFN-Î± in vitro and that Siglec-H ko mice produce more IFN-Î± after murine cytomegalovirus (mCMV) infection in vivo, leading to efficient clearance of the virus. Furthermore, ageing Siglec-H ko mice showed a mild form of systemic autoimmunity. In contrast, Siglec-H ko mice developed a severe form of systemic lupus-like autoimmune disease with strong kidney nephritis several weeks after a single mCMV infection. This induction of systemic autoimmune disease after virus infection in Siglec-H ko mice was accompanied by a type I interferon signature and fully dependent on type I interferon signaling. These results show that Siglec-H normally serves as modulator of type I interferon responses after infection with a persistent virus and thereby prevents induction of autoimmune disease. For microarray experiments gene expression profiles of total splenic cells from two wt and Siglec-H ko mice 26 weeks after infection with luciferase expressing murine Cytomegalovirus (5x105 pfu) or from two uninfected wt and Siglec-H ko control mice were analyzed

Modulation of immune cell reactivity with cis-binding Siglec-9 agonists

Project description:Primary inflammatory pathologies caused by phagocytes lead to numerous debilitating conditions, ranging from chronic pain to permanent blindness. Siglec-9 is an immunoinhibitory receptor expressed on many types of phagocytes and is a promising target for anti-inflammatory therapeutics. We developed a lipid-tethered glycopolypeptide that spontaneously inserts into cell membranes and specifically binds Siglec-9 in cis on the surface of cells. We demonstrate that when inserted in a cell membrane and cis-binding, but not as a soluble trans-binding agent, this glycopolypeptide and agonizes Siglec-9, inhibiting inflammatory activity in reporter systems, phagocytic cell lines, and primary human macrophages. Thus, membrane-tethered cis-agonists of Siglec-9 are a new modality for therapeutic suppression of immune cell reactivity.

The secretion of type I interferon of pDCs is modulated by Siglec-H, a DAP12 associated receptor on pDCs. We showed that Siglec-H deficient pDCs produce more of the type I interferon IFN-α in vitro and that Siglec-H ko mice produce more IFN-α after murine cytomegalovirus (mCMV) infection in vivo, leading to efficient clearance of the virus. Furthermore, ageing Siglec-H ko mice showed a mild form of systemic autoimmunity. In contrast, Siglec-H ko mice developed a severe form of systemic lupus-like autoimmune disease with strong kidney nephritis several weeks after a single mCMV infection.
