Abstract: The present disclosure relates to the engraftment and proliferation of cells in fat-associated lymphoid clusters (“FALCs” or “milky spots”), which may be used to generate functional ectopic tissue. The present disclosure further provides methods and compositions for grafting and proliferating cells, in FALCs by activating the lymphotoxin beta receptor (LT?R) and/or NF-?B-inducing kinase (NIK) signaling pathway. The present disclosure also provides for methods and compositions to establish ectopic liver tissue in FALCs (milky spots) and to use such ectopic liver tissue for therapeutic benefit, and provides methods and compositions to generate ectopic kidney tissue in FALCs, which can be used in a subject for therapeutic benefit.

Abstract: The present invention relates to methods of treating infectious, inflammatory and post-traumatic disorders by administering various compounds newly discovered to have TLR4 inhibitory activity. In addition to methods of treatment, the present invention further provides for pharmaceutical compositions comprising said compounds, together with a suitable pharmaceutical carrier. Because TLR4 is the most upstream receptor in the pro-inflammatory LPS signaling cascade, treatments of the invention, which inhibit or antagonize TLR4 action, may avoid the pitfalls associated with other cytokine inhibitors that act further down the pathway and accordingly play a less specific (and perhaps non-critical) role.

Abstract: The present disclosure concerns embodiments of an implantable perfusion device that can be implanted in an injured blood vessel to control bleeding without occluding the vessel. In one specific implementation, the perfusion device can be implanted percutaneously into a patient's descending aorta to control bleeding at the site of a ruptured portion of the aorta (known as torso hemorrhage) while still allowing for the antegrade flow of blood from a location upstream of the ruptured portion of the aorta to a location downstream of the ruptured portion of the aorta. The perfusion device can be left inside the patient as the patient is transported to a medical facility where the injury can be repaired. Following repair of the vessel, the perfusion device can be withdrawn from the patient.

Abstract: Recombinant transforming growth factor (TGF)-? monomers modified to inhibit dimerization and block TGF-? signaling are described. The recombinant TGF-? monomers lack the ability to bind and recruit TGF-? type I receptor (T?R1), but retain the capacity to bind the high affinity TGF-? type II receptor (T?RII), and in some instances, include mutations that increase their affinity for T?RII. Nucleic acid molecules and vectors encoding the recombinant TGF-? monomers are also described. Isolated cells, such as T cells, can be re-programmed with a TGF-? monomer-encoding nucleic acid or vector to secrete the monomer. Use of the recombinant TGF-? monomers and/or cells producing the recombinant TGF-? monomers, to inhibit TGF-? signaling, such as to treat disorders associated with aberrant TGF-? signaling, are also described.

Abstract: The present invention relates to methods and compositions for determining whether a subject having prostate cancer is at greater risk of developing progressive disease, and methods of treating the subjects. It is based, at least in part, on the discovery that approximately 90% of men carrying at least one of the following fusion genes: TRMT11-GRIK2, SLC45A2-AMACR, MTOR-TP53BP1, LRRC59-FLJ60017, TMEM135-CCDC67 and CCNH-C5orf30 experienced prostate cancer recurrence, metastases and/or prostate cancer-specific death after radical prostatectomy (each examples of “progressive prostate cancer”), while these outcomes occurred in only 36% of men not carrying any of these fusion genes. It is also based, at least in part, on the discovery that no patient studied survived five years without recurrence if their primary prostate cancer contained a TRMT11-GRIK2 or MTOR-TP53BP1 fusion gene. It is also based, at least in part, on the discovery that the protein encoded by the MAN2A1-FER fusion gene exhibits kinase activity.

Abstract: The invention relates to ex-situ biosensors that impedimetrically detect one or more target biomarkers of interest in bodily fluid sample derived from a patient. The biosensors include a multi-array of conducting material, such as platinum wires, having immobilized thereon antibody and/or aptamer that is selected to specifically and selectively bind to the one or more target biomarkers of interest. The biosensors are contacted with a portion of the bodily fluid sample, and the antibody and/or aptamer binds to the target biomarker(s) of interest in the bodily fluid sample. As a result, an electrochemical impedance signal is generated and therefore, a change in the electrochemical impedance is indicative of the presence of the target biomarker(s) of interest in the bodily fluid sample. The biosensors are point-of-care, on-demand devices that can be used in a medical environment, as well as in domestic and health emergency settings.
