Profiling microglia in a mouse model of Machado-Joseph disease
Campos, Ana Bela; Silva, Sara Carina Duarte; Fernandes, B.; Neves, Sofia Pereira; Marques, Fernanda; Castro, Andreia Cristiana TeixeiraMicroglia have been increasingly implicated in neurodegenerative diseases (NDs), and specific disease associated microglia (DAM) profiles have been defined for several of these NDs. Yet, the microglial profile in Machado–Joseph disease (MJD) remains unexplored. Here, we characterized the profile of microglia in the CMVMJD135 mouse model of MJD. This characterization was performed using primary microglial cultur...
Neuron-microglia contact-dependent mechanisms attenuate methamphetamine-induced...
Bravo, Joana; Ribeiro, Inês Moreira; Terceiro, Ana Filipa; Andrade, Elva B.; Portugal, Camila Cabral; Lopes, Igor M.; Azevedo, Maria M.; Sousa, MafaldaExposure to methamphetamine (Meth) has been classically associated with damage to neuronal terminals. However, it is now becoming clear that addiction may also result from the interplay between glial cells and neurons. Recently, we demonstrated that binge Meth administration promotes microgliosis and microglia pro-inflammation via astrocytic glutamate release in a TNF/IP<sub>3</sub>R2-Ca<sup>2+</sup>-dependent ...

However, it is now becoming clear that addiction may also result from the interplay between glial cells and neurons.

Astrocyte-derived TNF and glutamate critically modulate microglia activation by...
Canedo, Teresa; Portugal, Camila Cabral; Socodato, Renato; Almeida, Tiago Oliveira; Terceiro, Ana Filipa; Bravo, Joana; Silva, Ana IsabelMethamphetamine (Meth) is a powerful illicit psychostimulant, widely used for recreational purposes. Besides disrupting the monoaminergic system and promoting oxidative brain damage, Meth also causes neuroinflammation, contributing to synaptic dysfunction and behavioral deficits. Aberrant activation of microglia, the largest myeloid cell population in the brain, is a common feature in neurological disorders tri...
Maternal separation effects on mother rodents’ behaviour: A systematic review
Alves, Renata L.; Portugal, Camila Cabral; Summavielle, Teresa; Barbosa, Fernando; Magalhães, AnaMaternal separation (MS) is a widely-used paradigm to study the effect of early-life adversity on brain development and resilience to psychopathology. Most of the related literature focuses on MS impact on offspring, however, it should ideally also consider the impact of altered maternal behaviour caused by MS itself. This systematic review aimed at providing a comprehensive compilation of the effects of MS on ...
A mouse model reproducing the pathophysiology of neonatal group B streptococcal...
Andrade, Elva Bonifácio; Magalhães, Ana; Puga, Ana; Costa, Madalena; Bravo, Joana; Portugal, Camila Cabral; Ribeiro, Adília; Correia-Neves, MGroup B streptococcal (GBS) meningitis remains a devastating disease. The absence of an animal model reproducing the natural infectious process has limited our understanding of the disease and, consequently, delayed the development of effective treatments. We describe here a mouse model in which bacteria are transmitted to the offspring from vaginally colonised pregnant females, the natural route of infection. ...
