Abstract: The presently claimed invention relates to materials and methods for diagnosing a chronic inflammatory disease in a patient comprising testing a biological sample from the patient for a level of a first neurovascular biomarker of lymphatic activation and diagnosing the patient as having the chronic inflammatory disease if the tested level of the first neurovascular biomarker of lymphatic activation is less than a first normal level.

Abstract: Methods for using modulating agents to enhance or inhibit occludin-mediated cell adhesion in a variety of in vivo and in vitro contexts are provided. Within certain embodiments, the modulating agents may be used for cancer therapy or to increase immune cell infiltration into tumors. The modulating agents comprise at least one occludin cell adhesion recognition sequence or an antibody or fragment thereof that specifically binds the occludin cell adhesion recognition sequence. Modulating agents may additionally comprise one or more cell adhesion recognition sequences recognized by the other adhesion molecules. Such modulating agents may, but need not, be linked to a targeting agent, drug and/or support material.

Abstract: The present invention provides an isolated nucleic acid covalently linked to a photolabile caging group which reversibly prevents expression of the nucleic acid. The present invention further provides a method of selectively expressing a nucleic acid in a cell, comprising: a) covalently linking the nucleic acid to a photolabile caging group which reversibly prevents expression of the nucleic acid; b) introducing the nucleic acid of step (a) into the cell; and c) exposing the cell of step (b) to light, whereby exposure to the light unlinks the nucleic acid and the caging group and the nucleic acid is selectively expressed in the cell.

Abstract: Unique methods for treating edemas in living subjects are provided comprising administering an effective amount of an antamanide or an antamanide analogue to the subject. The methods offer prophylactic and therapeutic modes of treatment for both localized and systemic edemas. The antamanides and antamanide analogues may be applied topically or given parenterally; and may be employed with other diverse agents for treatment of both inflammatory and non-inflammatory edemas.

Abstract: Unique methods for treating interleukin-mediated edemas in living subjects are provided comprising administering an effective amount of a composition selected from the group consisting of phallotoxins, phallotoxin analogues, antamanide, or an antamanide analogue to the subject. The methods offer prophylactic and therapeutic modes of treatment for both localized and systemic interleukin-mediated edemas. The compositions of choice may be applied topically or given parenterally; and may be employed with other diverse agents for treatment of both inflammatory and non-inflammatory edemas.
