    Abstract COVID-19 has been declared a pandemic by the World Health Organization on March 11, and since then, more than 3 million cases and a quarter million deaths have occurred due to it. Lately, there is a growing evidence for an ophthalmologic symptom (conjunctivitis) to be connected with the disease. This seems to happen in early stages of the infection by SARS-CoV-2, and thus, it is of major importance to understand the mechanism through which the virus can facilitate such a symptom. Here, we are proposing a molecular mechanism through which the novel coronavirus could act in order to affect the eye and use it as another, secondary but alternative, point of entry to the host organism.

    Abstract COVID-19 has been declared a pandemic by the World Health Organization on March 11th and since then more than 3 million cases and a quarter million deaths have occurred due to it. The urge to find a resultful treatment or cure is now pressing more than any other time since the outbreak of the pandemic. Researchers all over the world from different fields of expertise are trying to find the most suitable drugs, that are already known to treat other diseases, and could tackle the process of SARS-CoV2 through which it invades and replicates in human cells. Here, we discuss five of the most promising drugs that can potentially play a major role in the treatment of COVID-19. While nicotine and ivermectin may be blocking transport abilities of the virus or its components, famotidine, remdesivir and chloroquine in combination with zinc ions can deactivate important enzymes needed for the replication of the virus. While clinical trials for some of these drugs have already started, it is common knowledge that lack of organization between countries, institutes and hospitals might slow down the whole process for an official treatment based in wide, randomized, placebo controlled trials.

    Abstract In neuroscience research, the efforts to find the model through which we can mimic the in vivo microenvironment of a developing or defective brain have been everlasting. While model organisms are used for over a hundred years, many more methods have been introduced with immortalized or primary cell lines and later induced pluripotent stem cells and organoids to be some of these. As the use of organoids becomes more and more common by many laboratories in biology and neuroscience in particular, it is crucial to deeper understand the challenges and possible pitfalls of their application in research, many of which can be surpassed with the support of state-of-the art bioengineering solutions. In this review, after a brief chronicle of the path to the discovery of organoids, we focus on the latest approaches to study neuroscience related topics with organoids, such as the use of assembloids, CRISPR technology, patch-clamp and optogenetics techniques and discuss how modern 3-dimensional biomaterials, miniaturized bioreactors and microfluidic chips can help to overcome the disadvantages of their use.

    Abstract Folate supplementation reduces the occurrence of neural tube defects (NTDs), birth defects consisting in the failure of the neural tube to form and close. The mechanisms underlying NTDs and their prevention by folate remain unclear. Here we show that folate receptor 1 (FOLR1) is necessary for the formation of neural tube-like structures in human-cell derived neural organoids. FOLR1 knockdown in neural organoids and in Xenopus laevis embryos leads to NTDs that are rescued by pteroate, a folate precursor that is unable to participate in metabolism. We demonstrate that FOLR1 interacts with and opposes the function of CD2-associated protein, molecule essential for apical endocytosis and turnover of C-cadherin in neural plate cells. In addition, folates increase Ca

    Abstract The balance between neural stem cell proliferation and neuronal differentiation is paramount for the appropriate development of the nervous system. Sonic hedgehog (Shh) is known to sequentially promote cell proliferation and specification of neuronal phenotypes, but the signaling mechanisms responsible for the developmental switch from mitogenic to neurogenic have remained unclear. Here, we show that Shh enhances Ca
