Poly(I:C)-Induced Maternal Immune Activation

Check if the same lab product or an alternative is used in the 5 most similar protocols
High molecular weight (HMV) poly (I:C) was purchased from InvivoGen. Poly (I:C) was dissolved in endotoxin-free saline solution, (4.0 mg/kg) and injected in the lateral vein of the tail of F0 pregnant dams. To assess the efficacy of poly (I:C) injection, all pregnant rats were weighed for the first 3 days after the administration of either poly (I:C) or endotoxin-free saline to evaluate potential weight loss as underlined by previous investigations (Zuckerman et al., 2003 (link)).
Apomorphine (APO, 0.125 mg/kg) (Merck Sigma-Aldrich) was dissolved in a solution containing 0.9% NaCl with 0.1 mg/ml ascorbic acid (pH 7.2) to prevent oxidation. D-Amphetamine sulfate (AMPH, 0.1 mg/kg) (Merck Sigma-Aldrich) was dissolved in a solution containing 0.9% NaCl. APO and AMPH were administered subcutaneously and intraperitoneally in an injection volume of 1 and 2 ml/kg, respectively.

Adaptively raised for 1 week, SD rats were randomly divided into two groups: the sham‐operated group (n = 6) and the 6‐OHDA‐lesioned group (n = 36). After deep anesthesia, the rats were stereotaxically injected with 3 μL 6‐OHDA (4 mg/mL in 0.02% ascorbic acid saline; Sigma) into the left striatum following our previously described protocol,
17 and the rats in sham group were injected with 3 μL vehicle (0.02% ascorbic acid saline).
The damage of rat dopaminergic neurons was assessed by apomorphine (APO, Sigma)‐induced rotation tests at the 5th, 8th, and 11th weeks of experiment.
17 At the end of the test on the 5th week, the 6‐OHDA‐lesioned rats were randomly divided into five treatment groups: (1) 6‐OHDA + L‐dopa (60 mg/kg) group,
20 (link) (2) 6‐OHDA + PIP (10 mg/kg) group, (3) 6‐OHDA + PIP (20 mg/kg) group, (4) 6‐OHDA + L‐dopa (60 mg/kg) + PIP (20 mg/kg) group, and (5) 6‐OHDA + madopar (75 mg/kg) group. The dosages of PIP used in the present study were safe for rats.
21 (link) Rats were treated once a day for 6 weeks. The 6‐OHDA group and sham group were treated with the same volume of substrate solution (0.5% CMC‐Na).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
