Abstract

BACKGROUND

Annexin 1 (ANXA1) has analgesic effects in inflammatory pain. We aimed to investigate the anti-nociceptive role of ANXA1, at the dorsal root ganglion (DRG) level, through an interaction with formyl-peptide-receptor-like 1 (FPR2/ALX).

METHODS

Inflammatory pain was evoked by injecting complete Freund's adjuvant (CFA, 50 μl) into the hindpaw of male Sprague-Dawley rats. The distribution of ANXA1 and FPR2/ALX in L4/5 DRGs was evaluated by immunofluorescence. The expression of ANXA1 was measured by western blot. The involvement of FPR2/ALX in the anti-nociception of ANXA1 was investigated by thermal (irradiant heat) and mechanical (von Frey filament) pain tests with intrathecal (i.t.) ANXA1-derived peptide (Anxa1(2-26)), FPR2/ALX agonist 5(S)-6(R)-7-trihydroxyheptanoic-acid-methyl-ester (BML-111), and antagonist N-t-Boc-Phe-Leu-Phe-Leu-Phe (Boc1).

RESULTS

ANXA1 and FPR2/ALX localized in the satellite glial cells and neurones in L4/5 DRGs. CFA treatment (n=20) increased ANXA1 expression in L4/5 DRGs within 7 days (P<0.01). I.T. Anxa1(2-26) (20 and 100 µg µl(-1)) and BML-111 (10 and 100 nmol) reduced CFA-induced thermal and mechanical nociception within 48 h (n=40) (P<0.05). However, i.t. Boc1 10 µg intensified inflammatory pain (P<0.05) and reversed the anti-nociceptive effect of Anxa1(2-26) (n=25) (P<0.05). Moreover, ANXA1 expression increased in L4/5 DRGs after i.t. Anxa1(2-26) (20 µg µl(-1)) (P<0.05) and BML-111 (10 nmol) (P<0.01) but decreased after i.t. Boc1 (10 and 100 µg) alone (P<0.01) or Boc1 (10 µg) co-injection with Anxa1(2-26) (20 µg µl(-1)) (P<0.05).

CONCLUSIONS

Endogenous ANXA1 expression at the DRG level is involved in CFA-induced inflammatory pain, and i.t. ANXA1 20 µg µl(-1) produces its anti-nociceptive effect through FPR2/ALX.

摘要

背景

膜联蛋白 1(ANXA1)在炎症性疼痛中具有镇痛作用。我们旨在通过与甲酰肽受体样 1(FPR2/ALX)的相互作用,在背根神经节(DRG)水平上研究 ANXA1 的抗伤害作用。

方法

通过向雄性 Sprague-Dawley 大鼠的后爪注射完全弗氏佐剂(CFA,50μl)来诱发炎症性疼痛。通过免疫荧光评估 L4/5 DRG 中 ANXA1 和 FPR2/ALX 的分布。通过 Western blot 测量 ANXA1 的表达。通过鞘内(i.t.)ANXA1 衍生肽(Anxa1(2-26))、FPR2/ALX 激动剂 5(S)-6(R)-7-三羟基庚酸甲酯(BML-111)和拮抗剂 N-t-Boc-Phe-Leu-Phe-Leu-Phe(Boc1)的热(辐射热)和机械(von Frey 纤维)疼痛测试来研究 FPR2/ALX 在 ANXA1 镇痛中的作用。

结果

ANXA1 和 FPR2/ALX 定位于 L4/5 DRG 的卫星神经胶质细胞和神经元中。CFA 处理(n=20)在 7 天内增加了 L4/5 DRG 中的 ANXA1 表达(P<0.01)。i.t. Anxa1(2-26)(20 和 100µg µl(-1))和 BML-111(10 和 100nmol)在 48 小时内减少了 CFA 诱导的热和机械性疼痛(n=40)(P<0.05)。然而,i.t. Boc1 10µg 加重了炎症性疼痛(P<0.05)并逆转了 Anxa1(2-26)(n=25)的抗伤害作用(P<0.05)。此外,i.t. Anxa1(2-26)(20µg µl(-1))(P<0.05)和 BML-111(10nmol)(P<0.01)后,L4/5 DRG 中 ANXA1 的表达增加,但 i.t. Boc1(10 和 100µg)单独(P<0.01)或 Boc1(10µg)与 Anxa1(2-26)(20µg µl(-1))共同注射后(P<0.05)降低。

结论

DRG 水平上内源性 ANXA1 的表达参与了 CFA 诱导的炎症性疼痛,i.t. ANXA1 20µg µl(-1) 通过 FPR2/ALX 产生其镇痛作用。
