Hypoxia is a characteristic of many solid tumors resulting from accelerated cellular proliferation and inadequate vascularization. HIF-1 is a transcription factor critical for maintaining cellular homeostasis in, and adaptively responding to, low oxygen environments. HIF-1 becomes activated through binding to the transcriptional co-activator protein p300. Disruption of the HIF-1/p300 interaction could potentially modulate HIF-1 activity.
Chimeric antigen receptors (CARs) with high affinity for mesothelin that can be used as an immunotherapy to treat cancers that express mesothelin, such as pancreatic cancer, ovarian cancer, and mesothelioma. The technology includes CAR constructs with one of three different mesothelin-specific antibody portions, including either the mouse-derived SS or SS1 antibody fragments or the human HN1 antibody fragment.
Melanoma is a particularly aggressive form of cancer primarily caused by over-exposure to sunlight. Although melanoma can strike at any age, the malignancy disproportionately impacts persons of advanced age, as these individuals often have decades of repeated exposure to harmful levels of ultraviolet radiation. Scientists at NIH among others have clarified the link between advanced melanoma and other malignancies and expression of SPANX-B.
One problem with the development of immunotherapy for cancer or other diseases is the inability to stimulate a sufficient immune response in patients to tumor associated antigens. The Linker Adapted for T Cell Signaling molecule (LAT) has been shown to be an important molecule in T cell signaling. The inventions described and claimed in this patent application illustrate a new supportive role for LAT which may be harnessed to improve a patient's immune response to tumor-associated antigens.
Tumors can develop unique genetic mutations which are specific to an individual patient. Some of these mutations are immunogenic; giving rise to autologous T cells which are tumor-reactive. Once isolated and sequenced, these neoantigen-specific TCRs can form the basis of effective adoptive cell therapy cancer treatment regimens; however, current methods of isolation are inefficient. Moreover, the process is technically challenging due to TCR sequence diversity and the need to correctly pair the a and b chain of each receptor.
This invention describes a general way to trigger the release of a bioactive small molecule from a targeting antibody. The key “trigger” is a fluorescent linker that is chemically disassembled upon irradiation with light in the near-IR range (~800 nm).
The invention relates to novel lipid-based nanoparticles (liposomes) for use in targeted, on demand and on site drug delivery. The particles include a wall surrounding a cavity, wherein the wall is comprised of:
phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG2000), and
Microduplications of the GPR101 gene (located on chromosome Xq26.3 and encodes a G-protein coupled receptor) can result in an excess of growth hormone causing gigantism, that has an onset in early childhood. It is also associated with the growth of sporadic growth hormone producing adenomas in some patients with acromegaly.
Griffithsin is a potent anti-viral protein with activity against HIV, HCV, Sars, HSV 1 & 2 and other viruses. It is active against HIV and HCV at picomolar concentrations. Griffithsin is moving into clinical trials as an anti-HIV microbicide. Based on the structure of griffithsin and the necessities of pharmaceutical product development and regulatory approval, certain mutations in the sequence of griffithsin have been generated which could add to the stability and solubility of the protein.
