The present disclosure provides modified bacteria and modified peptidoglycan comprising modified D-amino acids; compositions comprising the modified bacteria or peptidoglycan; and methods of using the modified bacteria or peptidoglycan. The modified D-amino acids include a bioorthogonal functional group such as an azide, an alkyne or a norbornene group. Also provided are modified peptidoglycans conjugated to a molecule of interest via a linker.

Disclosed are new recombinant isoforms of human-like lubricin or PRG4 glycoprotein having outstanding lubrication properties and a novel glycosylation pattern, and methods for their manufacture at high levels enabling commercial production.

Compositions comprising nanoparticles, nanoplexes or virus comprising isolated nucleic acid comprising nucleic acid encoding a mammalian, and methods of using the compositions, are provided.

Provided herein are polypeptides which include tenth fibronectin type III domains (.sup.10Fn3) that bind to glypican-3. Also provided are fusion molecules comprising a .sup.10Fn3 domain that bind to glypican-3 for use in diagnostic and therapeutic applications. Glypican-3 .sup.10Fn3 drug conjugates are also provided.

The present invention relates to therapeutic use of calreticulin in treatment of angiogenic eye diseases. Different treatment methods and pharmaceutical compositions comprising calreticulin are disclosed.

This disclosure relates to compositions and methods for treating cancer using chimeric antigen receptor T cells targeting glypican 3.

Disclosed are new recombinant isoforms of human-like lubricin or PRG4 glycoprotein having outstanding lubrication properties and a novel glycosylation pattern, and methods for their manufacture at high levels enabling commercial production.

The present invention relates generally to processes for production of heavily glycosylated recombinant proteins (e.g., mucins and mucin-like proteins, such as lubricin), the processes comprising culturing mammalian cells capable of producing a glycoprotein in a liquid medium in a system comprising one or more bioreactors, concentrating and purifying and formulating the glycoprotein, the purification comprising one or more steps of chromatography, an endonuclease step, and at least one step of viral inactivation. In certain aspects the invention relates to pharmaceutical compositions comprising purified recombinant human lubiricin, and methods of treating a subject in need thereof.

Provided are CAR-T compositions that are directed to GPC3, including chimeric receptors, and engineered immune cells to GPC3. The disclosure also provides vectors, compositions, and methods of treatment using GPC3 antigen binding molecules and engineered immune cells. GPC3 CAR compositions provided herein can be used for the treatment of certain cancers.

In some aspects, the present invention provides heteroclitic CALRMUT peptides designed and selected to elicit an immune response to CALRMUT in subjects with JAK2 mutant-negative myeloproliferative neoplasms, nucleic acid molecules encoding such peptides, compositions comprising such peptides or nucleic acid molecules, and various associated compositions and methods.
