Aquaporin1 (AQP1), located in the choroid plexus, is thought to be involved in the process of cerebrospinal fluid (CSF) production. Objective: The objective of this study is to examine the impact of hydrocephalus and cerebrospinal fluid (CSF) drainage on the expression of AQP1 in a mice model of hydrocephalus.&lt;strong&gt; Material and Methods&lt;/strong&gt;: Laboratory experimental study with six groups. Five test groups, one control group, and a rat model of hydrocephalus caused by kaolin were used in the experiment. &lt;strong&gt;Results:&lt;/strong&gt; Hydrocephalus in mice model induced by kaolin, and CSF drainage was performed on the 7&lt;sup&gt;th&lt;/sup&gt; and 14&lt;sup&gt;th&lt;/sup&gt; days group. Immunohistochemical analysis was conducted to examine the presence of AQP1 in the&lt;em&gt; choroid plexus&lt;/em&gt; using microscopes. The findings revealed a noticeable decrease in AQP1 expression levels in the &lt;em&gt;choroid plexus,&lt;/em&gt; which exhibited a semi-quantitative decline in correlation with the duration of hydrocephalus (p = 0.01). This decrease was observed when comparing the normal group with the hydrocephalus groups on the 7&lt;sup&gt;th&lt;/sup&gt;, 14&lt;sup&gt;th&lt;/sup&gt;, and 21st days following induction. However, after cerebrospinal fluid (CSF) drainage, there was a significant increase in AQP1 expression (p &amp;lt; 0.05). &lt;strong&gt;Conclusions: &lt;/strong&gt;This study shows the significant role of AQP1 in CSF production by comparing of AQP1 expression in the&lt;em&gt; choroid plexus &lt;/em&gt;of hydrocephalus mice model, with and without CSF drainage. AQP1 expression experiences downregulation in hydrocephalus mice model and upregulation after CSF drainage.&lt;/p&gt;
