Insetos dependem de palpos para detectar odores de comida, e seus palpos são acreditados para jogar um papel importante na especiação13,27. Os palpos são simples órgãos olfativos e estão recebendo crescente atenção como um atraente modelo de exploração da neuromolecular redes subjacente chemosensation28.
Inseto labellar e palpo SSRs foram realizados com sucesso em Drosophila melanogaster,...

Animais têm evoluído de uma gama de órgãos chemosensory que detetam sugestões químicas exógenas. Em insetos, os mais importantes órgãos de chemosensory são as antenas e os palpos. Nestes órgãos, diversos tipos de cabelos chemosensory, chamados chemosensory sensilas, são inervados pelos neurônios chemosensory (CSNs) dentro os pelos. CSNs em chemosensory sensilas reconhecem sugestões químicas específicas através de transdução de sinal de estímulos químicos para potenciais eléctricos que posteriormente são transferidos até o sistema nervoso central1,2,3 .
CSNs expressam vários receptores chemosensory [por exemplo, receptores de odorante (ORs)], geleificação receptores (IRs) e receptores gustativos (GRs) em suas membranas, que codificam exógenas sugestões químicas associadas com diferentes tipos de chemosensation 4,5,6. A caracterização da CSNs é a chave para a elucidação dos mecanismos celulares e moleculares de inseto quimiorecepção. Agora gravação única sensillum (SSR) é uma técnica amplamente utilizada para a caracterização de insecto CSNs nos sensilas antenais de muitos insetos, incluindo moscas7, traça8, besouros9, pulgões10, gafanhotos,11, e formigas,12. No entanto, poucos estudos têm aplicado um SSR a inseto palpos13,14,15,16,17, porque as estruturas particulares da suas sensilas fazem um gravação eletrofisiológicas difícil18.
Enxames de gafanhotos (Orthoptera) muitas vezes causam danos à lavoura grave e perda econômica19. Os palpos são acreditados para jogar um papel importante na seleção alimentar de gafanhotos20,21,22,23,24. Dois tipos de sensilas chemosensory são investigados por um microscópio eletrônico de varredura (MEV). Geralmente, chaetica 350 sensilas e 7-8 sensilas basiconica são observados em cada cúpula dos locust palpos18. Chaetica de sensilas são sensilas gustativas que detetam sugestões químicas não-volátil, enquanto sensilas basiconica têm uma função olfativa, sensoriamento sugestões químicas voláteis.
Em palpos de locust, os diâmetros das tomadas de cabelo da basiconica de sensilas (ca. 12 µm), são muito maiores do que aqueles de sensilas chaetica (ca. 8 µm)18,25. A parede cuticular do basiconica de sensilas sobre os palpos é muito mais espessa do que a de sensilas antenais18. Além disso, a cúpula do palpo tem conteúdo líquido dentro de uma cutícula altamente flexível. Estas características significam que uma penetração com um microeléctrodo e uma aquisição de sinais eletrofisiológicos boas é mais difícil do que para sensilas antenais. Neste trabalho, um protocolo SSR detalhado e altamente eficaz para locust palpo sensilas basiconica é apresentado com um vídeo.

single sensillum recordings for locust palp sensilla basiconica

Os palpos das peças bucais locust são considerados órgãos gustativos convencionais que desempenham um papel importante na seleção de alimentos de um gafanhoto, especialmente para a detecção de não-volátil sugestões químicas através de sensilas chaetica (anteriormente denominado terminais sensilas ou crista sensilas). Há crescente evidência de que estes palpos também têm uma função olfativa. Um receptor de odorante (LmigOR2) e uma proteína ligadora de odorante (LmigOBP1) foram localizadas nos neurônios e células de acessório, respectivamente, na basiconica de sensilas dos palpos. Sensillum única gravação (SSR) é usado para gravar as respostas dos neurônios receptores de odorante, que é um método eficaz para ligantes ativos sobre os receptores específicos odorante de triagem. SSR é usado em estudos funcionais de receptores de odorante no sensilas palpo. A estrutura do basiconica de sensilas localizado na cúpula dos palpos difere um pouco da estrutura das pessoas sobre as antenas. Portanto, ao realizar um SSR eliciado odorantes, alguns conselhos específicos podem ser útil para a obtenção de melhores resultados. Neste trabalho, é apresentado um protocolo detalhado e altamente eficaz para um SSR de inseto palpo sensilas basiconica.

Dois subtipos de sensilas (pb1 e pb2) sobre o palpo maxilar locust são identificados com base em dinâmica de resposta diferente de químicos odorantes (10% 1-nonanol e ácido nonanoico de 10%). Os neurônios no pb1 produzem significativamente mais picos de até 1-nonanol do ácido nonanoico enquanto os neurônios em pb2 são significativamente que menos ativado por 1-nonanol comparado com ácido nonanoico (Figura 4). Hexanal e E-2-Hexenal podem evocar um pa...
