Toward creating cell membrane glyco-landscapes with glycan lipid constructs
摘要:
Synthetic glycolipid-like constructs dispersible in biological media and capable of incorporating into cell membranes have the ability to create novel artificial glyco-landscapes on living cells. Using a variety of different glycans ranging from disaccharides to polysaccharides, together with different lengths and high hydrophilicity spacers, we created a series of synthetic glycolipid-like constructs. Contacting these constructs with live cells gave modified cells with controlled glycan density and/or altered biological function. The ability to also use these constructs as solutions to inhibit antibodies, toxins, and virions extends the potential diagnostic and therapeutic uses for these synthetic glycolipid-like constructs.

The invention relates to pharmaceutical compositions comprising α-Gal BOEL for use in treating patients with tumours. The invention also relates to methods of treating tumours using said compositions. The invention discloses that following intratumoural injection of α- Gal BOEL, binding of the natural anti-Gal antibody to de novo expressed tumoural α-Gal epitopes induces inflammation resulting in an anti-Gal antibody mediated opsonization of tumour cells and their uptake by antigen presenting cells. These antigen presenting cells migrate to draining lymph nodes and activate tumour specific T cells thereby converting the treated tumour lesions into in situ autologous tumour vaccines. This therapy can be applied to patients with multiple lesions and in neo-adjuvant therapy to patients before tumour resection. In addition to the regression and/or destruction of the treated tumour, such a vaccine will help in the immune mediated destruction of micrometastases that are not detectable during the removal of the treated tumour. The invention further teaches the enhancement of anti-tumour α-Gal BOEL treatment by the use of antibodies that inhibit the activity of immunological checkpoints molecules.
