    Abstract: Provided is a lung preservation composition comprising a non-carbonic buffered nutrient media, preferably a phosphate buffered nutrient media, and a dextran, optionally Dextran 40 and and optionally prostaglandin E1 (PGE1), and optionally at least one of alpha 1 antitrypsin (A1AT), an impermeant, optionally raffinose, an antioxidant, optionally glutathione, and necrostatin-1. Also described is a method of preserving a lung prior to and/or during transplant using said lung preservation composition, and kits comprising one or more components of the lung preservation composition.

    Abstract: The present disclosure is directed to HLA class II molecules having a higher affinity for CD4 than naturally occurring HLA class II molecules. In certain aspects, the HLA class II molecule comprises a DR beta chain having (i) an amino acid other than leucine at a position corresponding to amino acid residue 114 of SEQ ID NO: 1, (ii) an amino acid other than valine at a position corresponding to amino acid residue 143 of SEQ ID NO: 1, (iii) or both (i) and (ii). Certain aspects of the present disclosure are directed to nucleic acid molecules encoding the HLA class II molecules, vectors comprising the nucleic acid molecule, cells comprising the same, and methods of use thereof.
