본 연구는 소년원학교 여자 청소년을 대상으로 12주간의 혈액학적 면역기능에 도움 을 주는 통합적 무용동작심리치료(Dance movement therapy, DMT)를 적용하여 면역기능(Lymphocyte, T cell, B cell, NK cell, T helper cell, T suppressoer)의 변화를 알아보았다. 생물학적 요인과 감정은 신체움직임과 밀접한 연관성을 갖고 있 고 서로 상호작용하기 때문에 특히, 적응문제와 정서조절이 필요한 청소년들에게 DMT 접근을 하여 심리뿐만 아니라 신체적 변화를 확인하였다. 연구대상은 여자 소년 원생 8명으로 평균 연령은 17.75세, 신장은 157.63cm, 평균 체중은 59.25kg이다. DMT 프로그램을 주 1회, 90분씩 총 12주간 적용하였으며, DMT 처치 전과 후의 혈 액검사를 통해 신체 면역기능을 분석하였다. DMT 처치 전과 후의 Lymphocyte, T cell, B cell, NK cell, T helper cell을 비교분석 한 결과 통계학적인 유의한 차이가 나타났다(*p<.05). 이러한 결과는 DMT를 통해 비행청소년들의 염증이 감소되어 면역 력이 증가되었으며, 심리적 안정과 스트레스 감소로 인한 적응력 향상과 감정조절 능 력이 향상되었음을 시사할 수 있다.

Immune defense is indispensible for insect survival. However, uncontrolled and excessive immune responses would be highly detrimental and energy-consuming processes. An insect cytokine, plasmatocyte-spreading peptide (PSP), induces hemocyte-spreading behavior as well as activating phenoloxidase (PO) in the beet armyworm, Spodoptera exigua. A hemocyte transcriptome of S. exigua contains a partial sequence of a putative PSP-binding protein (SePSP-BP). SePSP-BP was expressed in all developmental stages especially in hemocytes and fat body. A quantitative RT-PCR showed that the bacterial infection significantly up-regulated the expression level of SePSP-BP. A double-stranded RNA specific to SePSP-BP (dsRNASePSP-BP) was injected and suppressed SePSP-BP expression even in response to bacterial challenge. The larvae treated with dsRNASePSP-BPsuffered high mortality to infection of nonpathogenic bacteria and prolonged high PO activity after the immune challenge. These results suggest that SePSP-BP may play a role in suppressing immune responses as a negative controller

We investigate the effects of the immune function (HI titer) in broilers fed diets containing Hermetia illucens (H. illucens) peptide extract over a 40-day period. Twenty-four broiler chicks (Arbor Acres, 1 d old) were divided into four groups and fed different diets (control, 0.1%, 0.5%, and 1% H. illucens peptide extract). To evaluate HI titer, all broilers were vaccinated with H9H2 vaccine subcutaneously on the lateral thorax, according to the manufacturer’s recommendations. Similar HI titer was observed with 1% H. illucens peptide extract treatment compared to the control after 40 days (p>0.01). Groups fed 0.5% H. illucens peptide extract demonstrated the most effective immune effects (p<0.01), followed by groups fed 0.1% H. illucens peptide extract. In conclusion, using 0.1% or 0.5% H. illucens peptide extract before or after vaccination improved HI titer immune function in broilers.
