A reverse transcriptase antiviral medication is administered for human T cell leukemia virus (HTLV)–infected patients.
a. True
b. False

검증된 단계별 안내

Step 1: Understand the role of reverse transcriptase in viral replication. Reverse transcriptase is an enzyme used by retroviruses to convert their RNA genome into DNA, which then integrates into the host cell genome.

Step 2: Identify whether human T cell leukemia virus (HTLV) is a retrovirus. HTLV is indeed a retrovirus, meaning it uses reverse transcriptase during its replication cycle.

Step 3: Recognize that reverse transcriptase inhibitors are antiviral medications designed to block the activity of reverse transcriptase, thereby preventing viral replication.

Step 4: Consider the clinical use of reverse transcriptase inhibitors. These drugs are commonly used to treat infections caused by retroviruses, such as HIV, and can also be used for HTLV infections.

Step 5: Conclude that administering a reverse transcriptase antiviral medication for HTLV-infected patients is a valid therapeutic approach, making the statement true.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Human T Cell Leukemia Virus (HTLV)

HTLV is a retrovirus that infects T cells and can cause adult T-cell leukemia/lymphoma. It integrates its RNA genome into the host DNA via reverse transcription, similar to HIV, but differs in disease manifestation and treatment approaches.

Reverse Transcriptase and Its Role in Retroviruses

Reverse transcriptase is an enzyme used by retroviruses to convert their RNA genome into DNA, enabling integration into the host genome. This enzyme is a key target for antiviral drugs in retroviral infections like HIV.

Antiviral Treatment for HTLV Infection

Unlike HIV, HTLV infections currently lack effective antiviral treatments targeting reverse transcriptase. Reverse transcriptase inhibitors used in HIV therapy are generally not effective or approved for HTLV, making supportive care and symptom management the main approach.
