Results suggest that the perisynaptic localization of brevican may be important to the short -and long-term structural plasticity that takes place in reaction to kainic acid [ 50 ]. Another study indicates that ADAMTS activity in the dentate outer molecular layer was examined for 2, 7 and 30 days after lesion. Results demonstrate that the synaptosomal-associated protein 25 SNAP , postsynaptic density protein 95 PSD and synaptophysin were declined in the developing frontal cortex of ADAMTS-1 deficient female mice, but not in male mice, suggesting in vivo ADAMTS1 knockout leads to sexual dimorphism in frontal cortex synaptic protein levels.
However, the decline in expression of synaptic proteins was not attended by deficits of learning and memory in the adult female ADAMTS1 null mice.
The important roles of ADAM9, , and in these processes such as APP amyloid cascade, functioning of pathogenetic processes, and subtypes of amyloid proteins are already known [ 22 , 63 , 64 ]. Additionally, several groups have been reported that the levels of ADAM10, which is especially effective on proteolytic processes involving APP, decreased in AD [ 65 , 67 , 68 ]. Tang et al. Authors thought that APP processing might be a useful biomarker for diagnosis of AD, and for monitoring drug responses in clinical trials [ 68 ].
Rosenberg and collaborators [ 70 ] reported that APP isoforms were quantitated with the use of Western blot methods in the blood from control and patients with AD. The mean ratio of the kD APP isoform to the kD APP isoform in blood platelets in patients with AD is significantly lower than that of control subjects in whom genotyping of apolipoprotein E was performed [ 70 ]. This results show that the correlation between peripheral and central compartments is extremely important.
Additionally, they demonstrated a decrease in the levels of ADAM10 plays an important in vivo role in the molecular pathogenesis of AD, and asserted that if its levels could be increased then important advances could be achieved in the treatment of AD [ 67 ]. Using immunohistochemical techniques, ADAM10 brain immunostaining is lower in different neocortical areas of the AD patients compared with control subjects [ 72 ].
Similar results were reported by Gatta et al. Bekris et al. These proteinases may be played a role in the pathogenesis of AD [ 49 , 75 ] and this process may contribute development of chronic neurodegenerative disorders [ 49 ]. Miguel et al. This finding may represent specific marker for the diagnosis of AD, and for the treatment of AD. Pehlivan et al. Furthermore, using immunohistochemical methods, ADAMTS4 expression was found to be related predominantly with astrocytes with elevated expression in the lesions of MS.
By using Western blot analyses, Ajmo et al. They found a noticeable discordance between the two, with the width of dispersal of the ADAMTS-originated brevican fragment being much wider that of WFA reactivity, which is a common reagent used to detect perineuronal nets of intact matrix and a marker which is thought to label regions of relative neural stability. Reelin has been known to be a glycoprotein crucial for brain development and functions that is largely expressed in brain [ 77 ] and is mandatory for neuronal functions included in learning and memory [ 78 , 79 ]. Decreased Reelin activity is associated with the onset of neuropsychiatric diseases such as AD [ 80 ].
These results demonstrate that the lack of Reelin is associated with increased phosphorylation of Tau and widespread formation of NFTs Fig. Further studies, including in human brain AD, will be needed to better comprehend the regulation of these proteases and their influence on Reelin-mediated signaling in the neurodegenerative disorders [ 57 , 82 ]. ADAMTS family members may be utilized to develop therapies for neurodegenerative and neurological disorders. Figure 2. In view of their enzymatic nature, they would serve to brain cells not just in terms of their physiological functions, but also in neurodegenerative processes.
Although growing evidences indicate that ADAMTS family enzymes are metalloproteinases with multiple functions, the exact expression profiling, regulation and function of ADAMTS in various pathophysiological processes of CNS, especially the signaling pathways and molecular events, remain to be delineated. As we fleetingly analyzed and discussed herein, much work on the transcriptional regulation of metalloproteinases including ADAMTS for regeneration and restoration processes of CNS tissue in the past 10 years was focused on individual transcription patterns of ADAMTS, and some of these studies relied solely on alters in phenotypes of the knockout mice to assess the function of different transcription patterns.
The molecular target genes of a couple of transcription factors in CNS are largely unknown. As we understand from previous great studies, ADAMTS might be an important pioneer molecule group for neurodegenerative diseases.

The Test of Infant Motor Performance TIMP is the current gold standard infant motor assessment, but rarely used by pediatricians during well-child visits due to lack of time and special training required. A short, standardized screening test administered to infants in the first months of life would target early intervention to those most at risk hence proving the importance of the test. This test has been conducted more widely and regularly in the US but has started gaining momentum with the NDT trained therapists all over the world thanks to its positive results.
The usefulness of a tool in a clinical setting depends on how much the clinician can rely on the data and how stable the data is over time. A good tool will have strong reliability, validity, and will be responsive to change. The content on or accessible through Physiopedia is for informational purposes only.
