Embodiment Construction

[0163] method

[0164] chemical reagent

[0165] Sodium cromolyn was supplied by AZTherapies, dissolved in PBS. A 100 mM solution was used for in vivo experiments. Dulbecco's PBS was used to dilute the solution for intraperitoneal injection as previously described, with a final dose of 6.3 mg / kg.

[0166] animal

[0167] 149 mice were used in this study. All animal care, husbandry, and experiments were performed in accordance with guidelines established by the Massachusetts General Hospital Subcommittee on Research Animal Care. These experiments were approved by the Massachusetts General Hospital Institutional Animal Care and Use Committee (2014N000018). All mice had free access to food and water. Mice were regularly assessed for dyskinesia and euthanized at the onset of severe paralysis (neurological score = 4, see Neurological Score below) to minimize distress, as previously described. Mice exhibiting mild paralysis (neurological score = 2) were fitted with water bo...

Abstract

Described herein are methods of treating neuron inflammation conditions, for example, amyotropic lateral sclerosis and prion disease, comprising administering a therapeutically effective amount of a combination of cromolyn or a cromolyn derivative compound and an anti-inflammatory agent.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 654,772, filed April 9, 2018, the entire contents of which are incorporated herein by reference. Background technique [0003] Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a specific disease that causes the death of neurons that control voluntary muscles. ALS is characterized by muscle stiffness, muscle twitching, and progressively worsening weakness due to a decrease in muscle size. This can cause difficulty speaking, swallowing, breathing and eventually death. [0004] ALS is estimated to affect as many as 30,000 people in the United States, with 5,000 new cases diagnosed each year. Most people with ALS are between the ages of 40 and 70, although the disease can occur at a younger age. Global ALS prevalence was independent of race, ethnicity, or socioeconomic group. ALS is responsible for an estimated 5 out of 10...
