Abstract
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by persistent articular inflammation and joint damage. RA was first described over 200 years ago; however, its etiology and pathophysiology remain insufficiently understood. The current treatment of RA is mainly empirical or based on the current understanding of etiology with limited efficacy and/or substantial side effects. Thus, the development of safer and more potent therapeutics, validated and optimized in experimental models, is urgently required. To improve the transition from bench to bedside, researchers must carefully select the appropriate experimental models as well as draw the right conclusions. Here, we summarize the establishment, pathological features, potential mechanisms, advantages, and limitations of the currently available RA models. The aim of the review is to help researchers better understand available RA models; discuss future trends in RA model development, which can help highlight new translational and human-based avenues in RA research.

Vicente S, Goins BA, Sanchez A, Alonso MJ, Phillips WT. Biodistribution and lymph node retention of polysaccharide-based immunostimulating nanocapsules. Vaccine 2014; 32:1685-92. [PMID: 24508040 DOI: 10.1016/j.vaccine.2014.01.059] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2013] [Revised: 01/14/2014] [Accepted: 01/21/2014] [Indexed: 10/25/2022]
Abstract
The adjuvant properties of polyglucosamine/squalene-based nanocapsules (PG-nanocapsules) associated with different subunit antigens has been previously reported. Thus, the aim of the present study was to monitor the biodistribution of PG-nanocapsules and their affinity for the draining lymph nodes after subcutaneous (s.c.) injection. The nanocapsules were efficiently radiolabeled with indium-111 ((111)In) (labeling efficiency of 98%). The diameter and zeta potential values of the unlabeled nanocapsules was preserved after the radiolabeling process and only 20% of the (111)In dissociated from the nanocapsules after 48h of incubation in serum. The radiolabeled nanocapsules and the control (111)InCl3 in saline solution (18.5MBq (500μCi) in 100μL) were injected s.c. in New Zealand White rabbits. The γ-scintigraphy imaging analysis revealed a slow clearance of the nanocapsules from the injection site and their progressive accumulation in the popliteal lymph node over time (3.8%±1.2 of the injected dose at 48h). Indeed, the clearance rate of the nanocapsules from the injection site was significantly slower than that of the control (free (111)InCl3), which rapidly drained into systemic circulation and accumulated mainly in excretion organs (i.e. kidneys and liver). In contrast, the biodistribution of nanocapsules was preferably limited to the lymphatic circulation. These results suggest that the immune potentiating effect previously observed for PG-nanocapsules is mainly due to the formation of a depot at the injection site, which was followed by a slow drainage into the lymphatic system and a prolonged retention in the lymph nodes.

[PMID: 20579894 DOI: 10.1016/j.apradiso.2010.06.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2010] [Revised: 05/22/2010] [Accepted: 06/01/2010] [Indexed: 10/19/2022]
Abstract
AIM The aim of this study was to evaluate early detection of temporomandibular joint (TMJ) inflammatory changes based on 1-thio-beta-d-glucose radiolabeled with technetium-99m. METHOD The method applied a TMJ inflammation model in rats followed by radiopharmaceutical synthesis, intravenous administration of (99m)Tc-1-TG and kinetic scintigraphy imaging. RESULTS Results show a significant difference of (99m)Tc-1-TG uptake between inflamed TMJ and the control joint. The biodistribution of (99m)Tc-1-TG by images showed the kidneys' excretion. CONCLUSION As conclusion, (99m)Tc-1-TG is a helpful tool in TMJ inflammatory process detection.
